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

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
