Question

Q51. Rahul and Sanjay ran 100 m in 11.25 and 12.5 seconds, respectively. If they start together, find how far was Sanjay from the finish time when Rahul completed his 100 m?

• A. (a) 30 m
• B. (b) 10 m
• C. (c) 22 m
• D. (d) 15 m

Answer 1

The correct option is B

(b) 10 m

$\frac{Lose{r}^{\prime }stime}{Winne{r}^{\prime }sdistance}=\frac{Starttime+beattime}{Bestdistance+startdistance}$

$\frac{12.5}{100}=\frac{0+1.25}{0+bestdistance}$

$Orbeatdistance=\frac{1.25\times 100}{12.5}=10m$
