Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 369 km

Given: 

Speed of first train = 15 km/h

Speed of second train = 26 km/h

One train has travelled 99 km more than the other.

Formula Used:

Distance = Speed × Time

Explanation:

Let the time of travel be 't' hours

Distance travel with a speed of 15 km/h = 15t

Distance travel with a speed of 26 km/h = 26t

According to the question

⇒ 26t -15t = 99

⇒ 9t = 99

⇒ t = 9 hours

The distance between stations = 15t + 26t

⇒ 15 × 9 + 26 × 9

⇒ 135 + 234 = 369 km
