Question

Two high-speed ferries leave at the same time from a city to go to the same island. The first ferry, the Cat, travels at 33 miles per hour. The second ferry, the Bird, travels at 27 miles per hour. In how many hours will the two ferries be 12 miles apart?

Answer 1

Cat 33 mph
Bird 27 mph
same direction in a straight line

catch up speed = 33-27= 6 mph
time = d/r
d= 12
t= 12/6 =2 hours
