Problem: a can run 288 metre in 28 seconds and b in 32 seconds . by what distance a beat b ?
Rationale: "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 = 288 / 32 = 9 m / s distance covered by b in 4 seconds = speed ã — time = 9 ã — 4 = 36 metre i . e . , a beat b by 36 metre answer is e"
annotated_formula: subtract(288, multiply(divide(288, 32), 28))
