In a 500 metres race, B starts 45 metres ahead of A, but A wins the race while B is still 35 metres behind. What is the ratio of the speeds of A to B assuming that both start at the same time?
25/21
A's speed- x B's speed- y time- t Distance for A-- 500m, Distance for B-- 500-45-35=420m xt=500 yt=420 x/y=500/420--> x/y=25/21
A and B take part in a 500 m race. A runs at 24 km per hour. A gives B a start of 40 m and still beats him by 15 seconds. What is the speed of B?
A starts working on a job and continues for 18 days and completes 40% of the work. Then, he employs B and together they worked for 24 days and completed the work. What is the ratio of efficiencies of A and B?
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?
Five athletes were competing in a race.
A finished before B but behind C.
D finished before E but behind B.
What was the finishing order?
In a race of 1.6 km, if A allows B a start of 160 m and the ratio of the speeds of A and B is 10 :9, then who wins and by what margin?
