A train leaves the station heading west on the tracks It takes the train 8 seconds to reach 80 miles per hour It completes the entire 160 mile trip in two hours Calculate the train's average speed?
Average speed = 80 miles per hour.
If you go halfway to the town which is 60 km away at the speed of 30 kmhour how fast do you have to go for the rest of the way to have the average speed of the entire way 60 kmhour?
It cannot be done. The trip is 60km. The half-way point is at 30 km. At 30km/hr, it takes 1 hour to go half-way. To average 60 km/hr, you would need to make the entire trip in 1 hour. So you have already consumed all your time.
A body travels with average speed of 20 km per hour and returns back from same route of average speed of 30 km per hour What is average speed of the trip?
Assume the trip to be 60km. Outward leg takes 3 hrs, homeward leg takes 2 hrs. Total distance 120km in 5 hours ie 24 kph.
You drive to Austin Texas 300 miles in 5 hours but the return trip takes you 7 hours what is your average speed for the trip in miles per hour?
You've done 600 miles in a total of 12 hours, therefore your average speed was 600/12 = 50 mph.
A car travels 275 miles at an average speed of 56 miles an hour how long of a trip is this?
275/56+4.9107hrs
Is the average of the total speed for an entire trip instantaneous speed?
by jumping
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.
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.
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.
Abdul while driving to school computes the average speed for his trip to be 20 kmh-1 On his return trip along the same route there is less traffic and the average speed is 30 kmh-1 What is the?
The overall average speed for the entire trip is not simply the average of 20 km/h and 30 km/h because Abdul spends more time at the slower speed. To calculate the overall average speed, you need to consider the total distance traveled and total time taken for the entire trip.
What is the calculated speed over an entire trip called?
If you divide the distance of your trip by the total time it took to make the trip, you calculate the average speed. That includes all the time you're stuck in traffic, gassing the car, and stopping to eat.
Can you determine how fast you were going at a midpoint of a trip by calculating average speed from the entire trip?
You can't. The average doesn't tell you anything about any single point during the trip. If I start out this morning and arrive somewhere 1,000 miles away tomorrow afternoon, my average speed for the entire trip could be 35 miles per hour. But at the mid-point of the trip ... either the mid-miles or the mid-time ... I could very well have been in a motel asleep. You can't tell.
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.
Explain whether during a trips cars instantaneous speed can ever be greater than its average speed?
Yes, during a trip a car's instantaneous speed can be greater than its average speed. This can occur if the car reaches its maximum speed at certain points during the trip, which would temporarily increase the instantaneous speed above the average speed calculated over the entire journey.
Julie walked to her friend's house to spend the afternoon She walked at 4 mph When she went home she ran at 6 mph so she wouldn't be late What is true about her average speed and average velocity?
Her average speed for the entire trip would be between 4 mph and 6 mph. Average velocity would consider both speed and direction, so it would take into account any changes in direction during the trip.
Can the average speed ever exceed the maximum speed for a trip?
No, the average speed will always be between the minimum and maximum speeds.
If A cyclist bikes x distance at 10 miles per hour and returns over the same path at 8 miles per hour. What is the cyclist's average rate for the round trip in miles per hour?
The average speed for the entire trip is 9mph.
