Question

A rifle fires a bullet at a target. The speed of the bullet is 600m/s. The target is located 400m away. How long does it take for the bullet to hit the target ?

Answer 1

0.67s

Explanation:

Given parameters:

Speed of bullet = 600m/s

Distance of target = 400m

Unknown:

Time taken for bullet to reach target = ?

Solution:

Speed is a physical quantity that expresses the rate of change of distance with time;

   Speed = $\frac{distance}{time taken}$

   Since time is unknown, we make it the subject of the expression;

   time = $\frac{distance }{speed}$ = $\frac{400}{600}$

   time = 0.67s
