Answer:
1/4 miles per minute
or
15 miles per hour
Step-by-step explanation:
Rember the equation
time * speed = distance
or
T * S = D
now plug in the known values
time = 20 min
or you could also say that the time is 1/3 hour
distance = 5 miles
20min * S = 5miles
divide by 20
S = 5 / 20
S = 1/4 mile per minute
another way of doing this with different units is
1/3 hour * S = 5 miles
divide 1/3 (same as multiplying 3)
s = 15 miles per hour
