Q1. A is 3 times as fast as B. If A gives B a head start of 80 meters, how long is the race course if they finish together?
Answer: 240 meters
Explanation: Since A is 3 times as fast as B, in the time B covers 1 unit, A covers 3 units. So, if B has a head start of 80 meters, A will cover 3 * 80 = 240 meters when B covers 80 meters. Hence, the race course is 240 meters.
