Question

Timmy is on a 2100 mile trip across the country. Over the last 12 hours of driving Timmy has traveled 720 miles. If he continues traveling at the same rate, how many more hours will it take him to complete his trip?

Answer 1

23 hours

Explanation:

So here we are trying to calculate Time which is Distance divided by Speed

Time =
`(Distance)/(Speed)`

Firstly, we have to calculate the Speed which is =
`(720)/(12)` = 60

This means that the speed is 60 miles per hour or 60 mph.

Then to find the total time we take the Distance and divide it by the Speed:

`(2100)/(60)` = 35

So this means that his total trip took 35 hours so lets subtract 12 hours to get how many more hours: 35 - 12 = 23 hours
