Question

The top speed of a missile was tested at 1764 km/h. How much distance will the missile cover in 1 second?
1. 510 m
2. 490 m
3. 485 m
4. 500 m

Answer 1

Correct Answer - Option 2 : 490 m

Given:

Speed of missile in km/h = 1764 km/h

Formula used:

km/h to m/s conversion = ('a' km/h × 5/18) m/s

Calculation:

∵ 1764 km/h = (1764 × 5/18) m/s

= 490 m/s

∴ The missile will travel 490 m in 1 second.
