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