Answer:
38.4 miles per hour
Step-by-step explanation:
30 miles in 45 minutes
18 miles in 30 minutes
Average speed = total distance / total time
= (30+18) / ( 45 min + 30 min)
= 48 miles / ( 1.25 hr ) = 38.4 miles per hour

Answer:
±sqrt(T*L/m)=v
Step-by-step explanation:
T=mv^2/L
We want to solve the equation for v
Multiply each side by L
T*L=mv^2/L
*L
T*L=mv^2
Divide each side by m
TL/m=mv^2/m
T*L/m=v^2
Take the square root of each side
±sqrt(T*L/m)=sqrt(v^2)
±sqrt(T*L/m)=v
