Question

Jessica is walking home from a friend's house. After two minutes she is 0.8 miles from home. Twelve minutes after leaving, she is 0.3 miles from home. What is her rate in miles per hour

Answer 1

Answer:

3 miles per hour

Step-by-step explanation:

Jessica is walking home from a friend's house.

After 2 minutes she is 0.8 miles from the home and after 12 minutes she is 0.3 miles away fro her house.

Her rate will be = (change in distance)/change in time

= (0.8-0.3)/(12-2)

= 0.5/10

= 0.05 miles per minute

Now we will convert timings from minutes to hour.

Or  = 0.05×60  

= 3 miles per hour
