Question

It usually takes Superman 180 minutes to fly from Earth to Krypton. He is running late today and has decided to fly at double the usual speed. How long will it take Superman to fly from Earth to Krypton at double the usual speed?

Answer 1

If Superman is flying at double his usual speed, he will cover the same distance in half the time. Therefore, it will take him 180 minutes divided by 2, which is 90 minutes, to fly from Earth to Krypton at double the usual speed.
