Q1. A is 3 times as fast as B. If A gives B a head start of 50 meters, how long is the race if they finish at the same time?
Answer: 75 meters
Explanation: Since A is 3 times as fast as B, for every 3 meters A runs, B runs 1 meter. To cover B's 50 meters head start, A needs to run 3 times the distance B runs. So, A runs 75 meters when B runs 25 meters, thus the race is 75 meters long.
