Without stoppages a train travels a certain distance with an average speed of 75 km/h and with stoppages it covers the same distance with an average speed of 65 km/h. How many minutes per hour does the train stop?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 8 min.
We know that,
Train stop time = (Speed of train without stoppage - Speed of train with stoppage)/Speed of train without stoppage × 60
Train stop time = (75 - 65)/75 × 60
Train stop time = 10/75 × 60
Train stop time = 8 min
