A and B run a km race. If A gives B a start of 100 m, A wins by 20 sec and if A gives B a start of 50 sec, B wins by 30 m. Then what is the time taken by A to run a km?

It takes A 196.9 seconds to run 1000 m. . We have two races. Race 1 is 1000 meter for A and 900 meter for B. A wins by 20 seconds. Race 2 is 970 meter for A and 1000 meter for B. . t = time (sec), v = speed (m/s), a and b are for A and B. And time = distance / speed . This gives us the following equations: For race 1: t1 = time for B to finish the race t1 - 20 = 1000 / va t1 = 900 / vb Thus: 900 / vb = 1000 / va + 20 . For race 2: t2 = time for B to finish the race (excluding the head start) t2 = 970 / va t2 + 50 = 1000 / vb Thus: 970 / va = 1000 / vb - 50 This can be rewritten to: 900 / vb = 873 / va + 45 . Now we have 900 / vb = 1000 / va + 20 = 873 / va + 45 Rewrite to: 127 / va = 25 => va = 127 / 25 = 5.08 meter/second. vb then is 4.15 m/s . Let's check: Race 1: A runs the 1000 m in 197 seconds. B runs the 900 m in 217 seconds => 20 second difference. Race 2: B runs the 1000 m in 241 seconds. Subtracting the head starts means A runs for 191 seconds. In that time A runs 970 meter and loses by 30 meter.
