Two buses start from two different cities that are 300 km apart and travel towards each other. The first bus's speed is 50 km/h, and the second bus's speed is 70 km/h. What is the time taken for them to meet?
Show answer & explanation
Correct answer: D
Explanation
Given:
Total distance = 300 km
Speed of the first bus = 50 km/h
Speed of the second bus = 70 km/h
Relative speed = 50 + 70
Relative speed = 120 km/h
Time = 300 ÷ 120
Time = 2.5 hours
