In a 200 m race, Rohan completes the race in 8 seconds and Vivan completes the race in 10 seconds. By how much distance Rohan beats Vivan?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 40 m
Given:
Race distance: 200 m
Time taken by Rohan: $t_R = 8$ sec
Time taken by Vivan: $t_V = 10$ sec
Speed of Rohan: $v_R = \frac{200}{8} = 25$ m/sec
Speed of Vivan: $v_V = \frac{200}{10} = 20$ m/sec
Distance covered by Vivan when Rohan finishes:
$d = v_V \cdot t_R = 20 \cdot 8 = 160$ m
Rohan beats Vivan by: $200 - 160 = 40$ m
