Question

A bus with 12 basketball players broke down in a town 20 miles from its destination. The coach’s car was available but could carry only 4 players at a time. Also, it could travel only 20 miles per hour because of the traffic. The players said they could walk at 4 miles per hour when they were not riding. Suppose the coach took 4 of them part way, came back for 4 more and took them part way, and then came back for the last 4. How could they all get to their scheduled basketball game at the same time?

Answer 5

| 4 miles | 4 miles | 4 miles | 4 miles | 4 miles |
----------------------------------------------
A B C D E F

coach picks up first 4 and drops them from A to D = 12 miles

coach then drives from D to B = 8 miles

coach picks up the next four and drives from B to E = 12 miles

coach then drives back from E to C = 8 miles

coach picks up last four and travels from C to F = 12 miles

so all in all he travels 52 miles in the car.

now just to clarify:

the first 4:

drove in the car 12 miles which took them 12/20 hours
and walked 8 miles which took 2 hours
= 2 12/20

the second 4 :
walked 4 miles which took them 1 hour
drove 12 miles which took them 12/20 hours
and walked another 4 miles which another 1 hour
= 2 12/20

the third 4:
they walked 8 miles which took them 2 hours
drove 12 miles which took them 12/20 hours
= 2 12/20

dont forget to give a million medals for this lol !
