Question

Joe needs to get to his house, which is 106 miles away in 2 hours. How fast does he need to drive? 48 mph 104 mph 0.019 mph 53 mph

Answer 1

53 mph

Explanation:

We need to give the answer in terms of miles per hour. This means that we need to find out how many miles Joe needs to travel in one hour. Therefore, this is a ratio problem.

We can set up a proportion where the unknown variable is the number of miles driven in one hour:

`(106)/(2) =(x)/(1)`

x is just 106/2, or 53. Therefore, Joe needs to travel 53 mph
