Juan roller skates 60 miles in 3 3/4 hours. what is his average speed in miles per hour?

16 mi/h

Step-by-step explanation:

1. To solve this problem you must use the formula shown below:

V=d/t

Where V is the average speed, d is the distance and t is the time.

2. You must substitute the value given in the probelm above into the formula:

(You have that 3 3/4 h=3+0.75 h=3.75 h)

V=60mi/3.75h

V=16 mi/h

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
