Answer:
The answer to your question is r = 44 mi/h
Step-by-step explanation:
Data
distance = d = 22 mi
speed = r = ?
time = t = 30 min
Formula
speed = distance / time or r = d/t
Process
1.- Convert minutes to hours
60 min ----------------------- 1 h
30 min ----------------------- x
x = (30 x 1) / 60
x = 30 / 60
x = 0.5 h
2.- Calculate the speed of the bus
speed = 22 mi / 0.5 h
speed = 44 mi/h
r = 44 mi/h
