How much time passes until the second bus catches up with the first bus?
Accepted Solution
A:
40 minutes. If the first bus started at 4:00, by the time the second bus left ( an hour later ) the first bus has already gone 40 miles. The second bus is going a mile a minute, since sixty divided by 60 ( the amount of minutes in an hour ) is 1, They need to go 40 miles, so it will take 40 minutes for the second bus to catch up with the first bus.
