Question

Two buses start at 9AM from two different places on a straight road. The buses travel towards each other at uniform speeds of 45 kmph and 55 kmph respectively. If the two places are 200 km apart, the buses will meet at

• A. 11 PM
• B. 10AM
• C. 10.30 AM
• D. 11 AM

Answer 1

The Correct Option is D

The relative speed of the two buses is: \[ 45 + 55 = 100 \, kmph \] The time taken for the buses to meet is: \[ \frac{200}{100} = 2 \, hours \] Since they start at 9 AM, they will meet at 9 AM + 2 hours = 11 AM. To calculate the time when two objects moving towards each other will meet, divide the distance by the sum of their speeds.
