Question : 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?
Option 1: 130 m
Option 2: 120 m
Option 3: 140 m
Option 4: 150 m
Correct Answer: 120 m
Solution : Given, In a 1200 m race, Rakesh reaches the final point in 36 seconds and Rajesh reaches in 40 sec According to the question, Rakesh beats Rajesh by (40 – 36) seconds = 4 seconds ⇒ Speed of Rajesh = $\frac{1200}{40}= 30$ m/s $\therefore$ Distance covered in 4 seconds by Rajesh = 30 × 4 = 120 m Hence, the correct answer is 120 m.
