Answer:
The average speed of Juan is 16 miles per hour.
Step-by-step explanation:
It is given that Juan roller skates 60 miles in [tex]3\frac{3}{4}[/tex] hours.
[tex]3\frac{3}{4}=\frac{12+3}{4}=\frac{15}{4}[/tex]
Speed formula:
[tex]\text{Average speed}=\frac{distance}{time}[/tex]
[tex]\text{Average speed}=\frac{60}{(\frac{15}{4})}[/tex]
[tex]\text{Average speed}=\frac{60\times 4}{15}[/tex]
[tex]\text{Average speed}=16[/tex]
Therefore the average speed of Juan is 16 miles per hour.
Answer: 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
