RRB NTPC · Question 95

A bus runs at 50 kmph. If the speed is increased by 10 kmph, it will cover 20 km more in the same time. Find the actual distance covered?

  1. 100 km

  2. 150 km

  3. 200 km

  4. 250 km

Show answer & explanation

Answer: (A) 100 km

Explanation

Let the time be t hours. At 60 km/h the bus covers 20 km more than at 50 km/h in the same time: 60t − 50t = 20, so t = 2 h. The actual distance = 50 × 2 = 100 km.
