When Patrick, Manu, and Amy participate in a race they realize that Patrick finishes the race in 60 seconds. Manu took 12 more seconds to finish the race. If Amy is twice as fast as Manu, how long did it take her to finish the race?
The time it took Manu to complete the race is 60 + 12 = <<60+12=72>>72 seconds
If Amy is twice as fast as Manu, then she takes half the time Manu did to finish the race, so Amy took 1/2 * 72 = 36 seconds.
