Question

In a 1600 m race, A beats B by 80 m and C by 60 m. If they run at the same time then by what distance will C beat B in a 400 m race?
Need explanation.​

Answer 1

Answer:

Assume A takes t seconds to finish the race.

Since A beat B by 80m, B travelled 1600m - 80m = 1520m in t seconds.

Similarly, C travelled 1600m - 60m = 1540m in t seconds.

Speed of A × t = 1600m

Speed of B × t = 1520m

Speed of C × t = 1540m

For the 400m race, assume time taken by A = t' seconds

Speed of A × t' = 400m = 1600 / 4      ( writing 400 as 1600 / 4 )

Speed of A × t' = (Speed of A × t ) / 4

t' = t / 4                    

Distance travelled by B in 400m race = Speed of B × t' = Speed of B × t / 4 = 1520 / 4 = 380

Distance travelled by C in 400m race = Speed of C × t' = Speed of C × t / 4 = 1540 / 4 = 385

So, distance between B and C in 400m race = 385 - 380 = 5m

Step-by-step explanation:

If A beats B by 80m and C by 60m, then C beats B by 20m in a 1600m race.

Then in a 400m race C can defeat B by 5m
