In a 300 m race, A reaches the finish point in 20 sec and B reaches in 25 sec. By how much distance A beats B ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 60 m
Speed of A = $\frac{300m}{20s}=15m/s$
Speed of B = $\frac{300m}{25s}=12m/s$
Distance covered by B in 20 seconds = $12×20=240m$
The distance A beats B by = $(300-240)m=60m$
