Rishabh Pant hits the ball. At the time of striking, the speed of the ball is 108 mile/hr. The speed of the ball remains constant till it reaches the boundary.  Ball covers the distance to reach boundary is 105 m. How much time taken by the ball to reach the boundary? (2 miles = 1 km)   Correct Answer 7 seconds 

Given: 

Speed of Ball at the time of striking = 108 mile/hr 

Distance between Rishabh Pant and boundary = 105 m 

Formula Used : 

Distance = speed × time 

x km/hr = 5/18 × x m/s 

Calculation: 

 ⇒ In km/hr , the speed of Ball = 108/2 = 54 km/hr 

⇒ In m/s, the speed of ball = 5/18 × 54 = 15 m/s

 ⇒ Distance = speed × time 

⇒ 105 = 15 × time
⇒ time = 7 sec 

∴ Time taken by ball to reach the boundary is 7 seconds
