Question from Gary, a parent: How many miles per hour was I driving to go 37 miles in 13 minutes |
It is only possible to work out your average speed. This is the number of miles travelled divided by the amount of time in hours taken to travel it. You travelled 37 miles in 13/60 of an hour, so your average speed is 37 miles divided by 13/60 hours, or about 170.8 miles per hour. It is not possible to say how fast you were going at any particular time. At any moment you could have been going faster or slower than that.
