Question

A bullet fired from a riffle travels at an average speed of 2880 km/h. It hits the target after 0.1 seconds. How far (in metre) is the target from the riffle?
1. 75
2. 80
3. 35
4. 40

Answer 1

Correct Answer - Option 2 : 80

Given:

Average speed of a bullet which is fired from the riffle = 2880 km/h

Formula used:

Distance = speed × time

Concept used:

m/s = (km/h) × (5/18)

Calculations:

Speed in m/s = 2880 × (5/18) = 800 m/s

Distance = 800 × 0.1 = 80 m

∴ The distance travel by the bullet to hit the target is 80 m.
