Question

Hari covers 100m distance in 36 seconds. Ram covers the same distance in 45 seconds. In a 100m race, Hari ahead from Ram is

• A. 20 m
• B. 30 m
• C. 25 m
• D. 40 m

Answer 1

Answer: (A)

20 m

Answer 2

Hari cover the Distance of $100$ m in $36$ sec and Ram cover the Distance of $100$ m in $45$ sec

Difference of timing between Hari and Ram is $9$ sec

Speed of Ram = $\frac{Distance}{Time}$ = $\frac{100}{45}$ $m/s$

Ram in 9 sec covered the distance = $Speed × Time$

= $\frac{100}{45} × 9$

= $20$ meters

**Therefore, Hari wins by 20 m to Ram. **
