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?
A. $$1\frac{{10}}{{19}}$$
B. $$\frac{{10}}{{19}}$$
C. $$\frac{9}{{19}}$$
D. $$\frac{9}{{10}}$$
Answer: Option B
Solution (By Examveda Team)

$$\eqalign{ & {\text{Speed of B}} = \frac{{50}}{5} = 10{\text{ m/sec}} \cr & {\text{Time same}} \cr & {\text{Then,}} \cr} $$

$${\text{Difference in speed}} = \frac{{200}}{1} - \frac{{10}}{1} = \frac{{10}}{{19}}$$
