Question

a car travels at an average speed of 52 miles per hour, how long does it take to travel 273 miles?

Answer 1

We define speed as the amount of distance you travel in an amount of time:

speed = (distance) / (time)

Similarly we could say:

time = (distance) / (speed) = (273 miles) / (52 miles/hour) = 5.25 hours

So it takes 5 hours and one quarter of an hour, or 5 hours and 15 minutes.

( .25 hours * (60 minutes / 1 hour) = 15 minutes)
