A train leaves Station A at 60 km/h. Another train leaves Station B, 180 km away, at 30 km/h toward Station A at the same time. How long will it take before they meet?

Hint
Their speeds add because they move toward each other.

Answer

2 hours.

Explanation

Their combined closing speed is 60 + 30 = 90 km/h. Time = distance / speed = 180 / 90 = 2 hours.

Step-by-Step Solution

Relative speed = 90 km/h.
Distance = 180 km.
Time = 180 ÷ 90 = 2 hours.
