55.231 MPH
212 miles per hour.
Traveling 117 miles in 2 hours and 15 minutes means the average speed is 52 miles per hour. (Divide 117 by 2.25)
The time it takes will depend on your average speed while traveling. In hours, it will be (490/speed in miles per hour).
Impossible to answer without knowing an average speed. Big difference between traveling by car and traveling by jet plane.
The average speed is exactly (100 miles per 5.5 hours).In a more familiar unit:100/5.5 = 182/11 miles per hour = 18.182 mph (rounded)
212 miles per hour.
40
420 mph
The average speed is 120 miles per hour.
Traveling 117 miles in 2 hours and 15 minutes means the average speed is 52 miles per hour. (Divide 117 by 2.25)
An average of 45 mph.
The time it takes will depend on your average speed while traveling. In hours, it will be (490/speed in miles per hour).
The vehicle would be traveling at 125 mph.
There is something wrong with your units. Anyway, to calculate the average speed, you need to divide the distance by the time. If (for example) the distance is in miles, and the time in hours, then you get a speed in miles per hours.
Impossible to answer without knowing an average speed. Big difference between traveling by car and traveling by jet plane.
If you mean the average speed, simply divide the total distance by the total time.
Divide 180 by the average speed (60) and you will have your answer.
