Mrs Hammond is running from a dinosaur at a constant rate of 4/5 of a mile in 1/5 of an hour. At this rate how long would it take her to run a full mile to the speedway to refill her slurpie?

AS you can see: 4/5 mile = 1/5 hour

You have to divide by 4 to get a unit rate

So, (4/5÷4) = 1/5 mile, and (1/5÷4) = 1/20 hour

1/5 mile = 1/20 hour

Now you have to multiply by 5 to figure out the total time per mile

(1/5*5) = 1 mile, and (1/20*5) = 5/20 hour

Then, if you simplify you get: 1 mile = 1/4 hour

It would take Hammond 1/4 of an hour to refill her slurpie.

Hope this helped!
