Tom walks half a distance at 4mph and runs back the other half at 12 mph what is his average speed for the entire trip?
To calculate the average speed for Tom's entire trip, we can use the formula for average speed, which is total distance divided by total time. Let's assume the total distance is (d). Tom walks half the distance ((d/2)) at 4 mph and runs the other half at 12 mph. The time taken to walk is ((d/2) / 4 = d/8) hours, and the time taken to run is ((d/2) / 12 = d/24) hours. The total time is (d/8 + d/24 = 3d/24 + d/24 = 4d/24 = d/6) hours, so the average speed is (d / (d/6) = 6) mph.

What was Erin's average speed for the entire trip?
To calculate Erin's average speed for the entire trip, you'll need the total distance traveled and the total time taken. The average speed can be found using the formula: average speed = total distance / total time. If you provide the specific distance and time values, I can help you compute the average speed.
Is speed that does not vary is called average speed?
No, speed can vary and one can still calculate the average speed of an entire trip. Average speed is equal to the change in distance divided by the change in time.
How do you calculate average speed with speed-time graph?
To calculate average speed using a speed-time graph, first identify the total distance traveled and the total time taken. The area under the speed-time curve represents the distance, while the total time is represented on the x-axis. Use the formula: average speed = total distance / total time. This gives you the average speed over the entire duration represented in the graph.
Can you determine how fast you were going at the midpoint of a trip by calculating average speed for the entire trip?
No, you cannot determine the exact speed at the midpoint of a trip solely by calculating the average speed for the entire trip. Average speed is the total distance traveled divided by the total time taken, which does not account for variations in speed during different segments of the journey. The midpoint speed could be higher or lower than the average speed, depending on how speed changed throughout the trip.
How do they calculate average speed?
Average speed = (distance covered) divided by (time to cover the distance)
How is instantaneous speed different from average?
The average speed is the speed that it takes to travel a certain distance in a certain time. Average speed is determined by dividing the distance traveled by the time taken to get there. Instantaneous speed is a certain speed at any given time.
Is speed that does not vary is called average speed?
No, speed can vary and one can still calculate the average speed of an entire trip. Average speed is equal to the change in distance divided by the change in time.
Dividing the total distance by the total time is what?
Dividing the total distance by the total time gives you the average speed. This calculation tells you how fast you are moving on average throughout the entire journey.
What measures the speed during a entire trip?
The average speed measures the speed during an entire trip. It is calculated by dividing the total distance traveled by the total time taken.
If you consider the total distance and total time for a trip are you calculating an instantaneous speed or constant speed average speed or non-uniform speed?
When you consider the total distance and total time for a trip, you are calculating average speed. Average speed is the total distance traveled divided by the total time taken. It gives you an overall idea of how fast an object moved during the entire trip, regardless of any fluctuations in speed that may have occurred.
What was Jack's average speed for the entire ride?
It was (the total distance he covered) divided by (the total time he spent riding).
Is the total distance divided by the total time?
Acceleration equals velocity divided by time i.e a=v/t The S.I unit of Acceleration is m/s2
How would you find the average speed of a cyclist are out in entire race?
To find the average speed of a cyclist over an entire race, you would divide the total distance covered by the cyclist by the total time taken to complete the race. This calculation will give you the cyclist's average speed throughout the race.
How do you find the average speed of a cyclist throughout an entire race?
To find the average speed of a cyclist throughout an entire race, you would divide the total distance covered by the cyclist by the total time taken to complete the race. This will give you the average speed in units such as miles per hour or kilometers per hour.
What is the formula to find the average speed of a given distance and time?
Distance = time * average speed (velocity) Average speed = Distance/time
How would you find the average speed of a cyclicst throughout an entire race?
You divide the total distance by the total time.
How do you tell the average of speed?
v= s/t v= speed s=path t=time to calculate the average speed you need the path the object is moving on and the time it took to pass it
