Question

Jessica is walking home from a friend's house. After two minutes she is 1.2 miles from home. Twelve minutes after leaving, she is 0.7 miles from home. What is her rate in miles per hour?

mph

Answer 1

3.0 mph

Step-by-step explanation:

The rate would be Change in distance/Change in time = 1.2-0.7/12-2

When you simplify that, it gives you 0.5/10 = 0.05

To convert 0.05 minutes into hours, you multiply by 60.

0.05 x 60 = 3.0 mph
