The speed of 45 km/h states that in every hour = 60 minutes = 3600 seconds the car travels 45 km.
So in 6 seconds it travels 6/3600 = 1/600 this distance, that is:
45 x 1/600
= 45/600
= 3/40
= 0.075km
= 75m.
Total distance = 75 km time = 3 hours average speed = 75km/3hrs = 25 km/hr
well we know that we have two speeds and a time. So, initial speed = 80 final speed = 60 change in time = 6 Now acceleration in this case will be measured in kilometers per hour per second (i.e. every x seconds, y kilometers per hour are gained in speed) So we simply apply the formula Acceleration = (final speed - initial speed)/ change in time = (80 - 60)/6 = 20/6 = 3.6666667 km/h/s
Average speed is 65 mph.
136.7 mph
Zero, cars are parked more often than they are driven.
75 miles per hour. the average speed is how many miles (or kilometers, inches, centimeters etc.) u can travel in one hour, seconds, etc. For cars, it is usually miles per hour or km per hour.
Total distance = 75 km time = 3 hours average speed = 75km/3hrs = 25 km/hr
well we know that we have two speeds and a time. So, initial speed = 80 final speed = 60 change in time = 6 Now acceleration in this case will be measured in kilometers per hour per second (i.e. every x seconds, y kilometers per hour are gained in speed) So we simply apply the formula Acceleration = (final speed - initial speed)/ change in time = (80 - 60)/6 = 20/6 = 3.6666667 km/h/s
At least 2. At freeway speed, 3-5.
if you mean are Canadian car's speed measured in kilometers then yes because Canada uses the metric measurement system
Between 80mph and 120 mph, high performance cars were usually between a top speed of 100 to 140.
To find the average speed, add up all the speeds and then divide by the number of speeds given. (45 + 37 + 34 + 40) / 4 = 39 mph. Therefore, the average speed of the cars is 39 mph.
distance in miles divided by time in hours equals MPH. or more simply put velocity X time = distance. For shorter distances you can use meters divided by seconds = mps
Average speed is 65 mph.
3 ms-2
The cars avg speed would be 66 km/ 3 hr which is 22kmh
Extremely fast: 1 hour = 3600 seconds speed = distance/time = 1 mi / 45 s = 1/45 mi/s = 1/45 mi/s x 3600 s/hr = 3600/45 mi/hr = 80 mph!
