5:50 AM
Step-by-step explanation:
First, we find the time it takes to drive.
speed = distance/time
time * speed = distance
time = distance/speed
time = ? (unknown)
distance = 20 miles
speed = 40 mph
time = distance/speed = (20 miles)/(40 mph) = 0.5 hour
0.5 hour * 60 min/hour = 30 minutes
It takes 30 minutes to drive. Now we add 30 minutes to 5:20 AM to find the arrival time.
5:20 AM + 0:30 = 5:50 AM
