The speeds of two bodies are in the ratio 2 : 3. If the difference in the time taken to cover 50 m is 10 sec, then find the difference in their speeds.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. m/sec
Given that
The speeds of the two bodies are 2x and 3x .
The difference in time taken to cover 50 m = 10 sec
50/2x - 50/3x = 10
50/6x = 10
x = 5/6
Hence, the differences in their speed = x = 5/6 m/s
