Question

Kylie went on a road trip with her family. They traveled at an average speed of 50 miles per hour for 2.5 hours and then traveled at an average speed of 65 miles per hour for 3 hours. What was the total distance in miles that Kylie’s family traveled during this time?

Answer 1

Answer: 320 miles

Step-by-step explanation:

First, we need to make an equation. However, we can’t fight to label the variables:

t = total number of miles

h = number of hours

Now let’s set up our equation:

t = 50h + 65h

The good thing is that we know how many hours each speed was held for, so we can substitute it in the equation.

t = 50(2.5) + 65(3)

t = 125 + 195

t = 320

Therefore, the total number of miles traveled is 320.
