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

The Correct Option is A

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.
