Question:

A man walking at a rate of 4 km/h crossed a tunnel in 18 minutes. What is the length of the tunnel in meters?

Options:

1800

1400

1200

1600

Correct Answer:

1200

Explanation:

Speed = 4 km/h

4 km/h = 4 × \(\frac{5}{18}\) = \(\frac{10}{9}\) m/sec

Time = 18 minutes = 18 × 60 sec = 1080 sec

Distance = Speed × Time

= \(\frac{10}{9}\) × 1080

= 1200 m
