In a 1200 m race, Rakesh reaches the final point in 36 seconds and Rajesh reaches in 40 sec. By how much distance does Rakesh beat Rajesh?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 120 m.
Distance is constant
So, the time ratio of time = 36 : 40
Thus, the ratio of speed = 40 : 36
By how much distance does Rakesh beat Rajesh = Total distance/Rajesh speed × difference between their speed
⇒ 1200/40 × 4
⇒ 1200/10 = 120 m
Thus, Rakesh beat Rajesh by 120 m.
