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

Answer:

The average speed of Juan is 16 miles per hour.

Explanation:

It is given that Juan roller skates 60 miles in
3(3)/(4) hours.


3(3)/(4)=(12+3)/(4)=(15)/(4)

Speed formula:


\text{Average speed}=(distance)/(time)


\text{Average speed}=(60)/(((15)/(4)))


\text{Average speed}=(60* 4)/(15)


\text{Average speed}=16

Therefore the average speed of Juan is 16 miles per hour.
