Question

Olive walks at a rate of 4 miles per hour. She lives 2 miles from the new station. How long will it take her or walk home from the new station?

Answer 1

Half an hour

4 miles = 1 hour

2 is half of four so = 30 minutes

Answer 2

Olive walks at a rate of 4 miles per hour, and she lives 2 miles from the new station. Set the ratio:

4/1 = 2/x

Cross multiply

4x = 2

Isolate the x. Divide 4 to both sides

4x/4 = 2/4

x = 2/4 or 1/2

It will take her 1/2 hour to get to the new station.

hope this helps
