Dominik [7]

Answer:

Step-by-step explanation:

The average speed = Total distance / Total Time

Distance at 45 m/hr.

r = rate = 45 miles / hour

d = r * t

d = 45 * 1/3 = 15 miles.

Average Speed going home.

t =  30 minutes

t = 30 min / 60 min // hour = 1/2 hours

r = 15 miles / 1/2 = 15 * 2 =  30 miles / hr.
