a can run 192 metre in 28 seconds and b in 32 seconds. by what distance a beat b?
subtract(192, multiply(divide(192, 32), 28))
"clearly , a beats b by 4 seconds now find out how much b will run in these 4 seconds speed of b = distance / time taken by b = 192 / 32 = 6 m / s distance covered by b in 4 seconds = speed ã — time = 6 ã — 4 = 24 metre i . e . , a beat b by 24 metre answer is c"
