Question

In a 1000 m horse race Harsh’s horse runs at a speed of 16.66 m/s. If Harsh gives a start of 40 m to Mohit’s horse and still beats him by 12 seconds, what is the speed of Mohit’s horse?

• A. 10 m/s
• B. 12.5m/s
• C. 13.33 m/s
• D. 15 m/s

Answer 1

The correct option is C

13.33 m/s

Time taken by Harsh's horse to cover 1000 meters = 60 seconds,

$\Rightarrow$ Since Harsh gives a start of 40 m then time takes by Mohit's horse = 72 seconds

$\Rightarrow$ Mohit's horse takes 72 seconds to cover 960 meters

$\Rightarrow$ Speed of Mohit's horse = $\frac{960}{72}$ = 13.33 m/s
