Question

A rocket travels 2500 km in 50 hours. How many kilometers will the rocket travel in 7 hours?

• A. 50
• B. 350
• C. 300

Answer 1

The correct option is B 350

A rocket travels 2500 km in 50 hours

The rocket travel in one hour, = $\frac{\text{total kilometers travelled}}{\text{total hours taken}}$

= $\frac{2500}{50}$

The rocket travels 50 kilometers in an hour
$\therefore$ Kilometers travelled in 7 hours =50 × 7
=350
