Two cars, one from City M and another from City N, which are 450 km apart, start moving towards each other. The first car travels at a speed of 50 km/h, and the second car travels at a speed of 40 km/h. If they start at the same time, how far from City M will they meet?
Show answer & explanation
Correct answer: A
Explanation
Given:
Total distance = 450 km
Speed of the first car = 50 km/h
Speed of the second car = 40 km/h
Formula:
Time = Distance ÷ Relative Speed
Relative Speed = 50 + 40 = 90 km/h
Time = 450 ÷ 90 = 5 hours
Distance of the car from City M
= 50 × 5 = 250
They will meet 250 km from City M.
