Answer:
Average speed=52 miles per hour
Step-by-step explanation:
The expression for calculating the average speed is as follows;
S=D/T
where;
S=average speed
D=distance traveled
T=time taken
In our case;
S=unknown
D=130 miles
T=2 1/2 hours=2.5 hours
replacing;
Average speed=130/2.5=52 miles per hour
Average speed=52 miles per hour
