Stephanie walks 2/5 miles in 1/4 our what is Stephanie speed in miles per hour

1 3/5 miles per hour

Step-by-step explanation:

Distance = rate * time

We know the distance and the time

2/5 miles = rate * 1/4 hour

Divide by 1/4

2/5 : 1/4 = rate * 1/4 : 1/4

Copy dot flip

2/5 * 4/1 = rate

8/5 = rate

1 3/5 miles per hour is the rate

2:5=0.4

1:4=0.25

0.4:0.25=0.016

so she walks at a rate of 0.016 miles per hour
