Question
Ratio of speeds of ‘A’ and ‘B’ is 4:9,
respectively. If they participate in a 270-metre race and ‘B’ gives ‘A’, a head start of ‘m’ metres, then they finish the race at the same time. Find the value of ‘m’.Solution
Let the distance covered by ‘A’ in the time ‘B’ covers 270 metres be ‘x’ metres (x/270) = (4/9) Or, x = 120 So, m = 270 – 120 = 150 metres
