Question
Ratio of speeds of ‘A’ and ‘B’ is 2:3,
respectively. If they participate in a 450-metre race and ‘B’ gives ‘A’, ahead 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 450 metres be ‘x’ metres (x/450) = (2/3) Or, x = 300 So, m = 450 – 300 = 150 metres
