In a linear race of 1000 m, A beats B by 50 m or 5 seconds. What is the difference between the speeds (in m/s) of A and B? |
$1\frac{10}{19}$ $\frac{10}{19}$ $\frac{9}{19}$ $\frac{9}{10}$ |
$\frac{10}{19}$ |
Formula speed :- Speed = \(\frac{Distance }{Time}\) According to question , A beats B by 50 m or 5 sec i.e B covers 50 m in 5 sec Difference in speed of A and B = \(\frac{200}{19}\) - 10 = \(\frac{10}{19}\) m/sec |
