During the middle of a family picnic, Barry Allen received a message that his friends Bruce and Hal to be saved. Barry promised his wife Iris that he would be back in exactly 5 minutes. From that that picnic
location, Barry runs at a speed of 600 m/s for 2 minutes at a heading of 35° north of west to save Bruce.
He then changed his heading to 30° west of north, slows down to 400 m/s and runs for 1 minute to save
Hal. (The changes in speed are essentially instantaneous and not part of solving this problem).
