[Solved] In a 1 km race, A beats B by 50 m or 5 secs. How long does A

Given: Track length = 1 km Formula used: Distance = Speed× Time Calculation: "A" beats "B" by 50 m or 5 sec, means "B" covers 50 m in 5 sec Speed of "B" = 50/5 = 10 m/s Time to cover 1000 m = 1000/10 = 100 sec "A" beats "B" by 5 sec means "A" reach 5 sec early Time taken by "A" to complete the race = 100 –5 = 95 sec ∴ Time taken by "A" to complete the race is 95 sec

In a kilometre race, A beats B by 30 seconds and B beats C by 15 seconds. If A beats C by 180 metres, the time taken by A to run 1 kilometre is

A beats B by 3 0 seconds, B beats C by 1 5 seconds ∴ A beats C by ( 3 0 + 1 5 ) seconds = 4 5 seconds ⇒ Time taken by C to travel 1 8 0 m = 4 5 seconds ⇒ Time taken by C to cover the distance of 1 k m ( 1 0 0 0 m ) = 1 8 0 4 5 ​ × 1 0 0 0 = 2 5 0 s e c o n d s ∴ Required time taken by A to cover the distance of 1 km = ( 2 5 0 − 4 5 ) s e c = 2 0 5 s e c .

In a kilometer race A beats B by 40 meters or by 5 seconds What is the time taken by A over the cour...... @ abhipedia Powered by ABHIMANU IAS

None of these.Explanation: A runs 1km = 1000 m, it means B runs 1000 - 40 = 960 meters Time is taken by B for 40 meters = 5 seconds Time is taken by B for 960 meters = × 960=120 seconds The time in which B covered 960 meters, A has covered 1000 meters. ∴ A's time over the course = 120 seconds = 2 minutes
