Question

. Cole rode his bike for 45 miles at a rate of 15 miles per hour. How long did it take him to ride the 40 miles?

Answer 1

Note what information you have been given.

You have been given the speed of his bike, which is 15 miles per hour. You have also been given the distance he rode his bike: 45 miles.

You have to find how long it takes him to ride 40 miles.

It can be noted that "Cole rode his bike for 45 miles" is an unnecessary piece of information, since we only need the speed to calculate how long it takes to travel a certain distance. So, we can ignore the 45 miles part.

The problem simplified is: If 15 miles can be traveled in an hour, how long will it take to travel 40 miles?

This can be solved by dividing 40 miles by 15 miles per hour, giving the answer of 2
`(2)/(3)` hours.

Answer 2

3 hours. Because 15 miles x 3 hours =45 miles. Hope this helps.
