Question

A train covers 1200 km in 10 hours. The distance it covers in 1 minute is

• A. 120 km
• B. 2 km
• C. 6 km
• D. 60 km

Answer 1

The correct option is B 2 km

$\text{Distance covered in 10 hours}=1200\text{km}$

$\text{Distance covered in 1 hour}=\frac{1200}{10}=120\text{km}$

$\text{1 hour = 60 minutes}$

$⟹\text{Distance covered in 60 minutes}=120\text{km}$

$\text{Distance covered in 1 minute}=\frac{120}{60}=2\text{km}$
