Two cars start from the same point and travel in opposite directions. If one car travels at 40 km/h and the other at 50 km/h, after 5 hours, how far apart are they?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 450 km.
Since the two cars are traveling in opposite directions, So
Relative speed = 40 + 50 = 90 km/hr
We know that,
Distance = Speed × Time
Distance = 90 × 5 = 450 km
Thus, after 5 hours, the two cars are 450 km apart
