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 ? |
50 m 60 m 75 m 40 m |
60 m |
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 = $(300-240)m=60m$ |
