Q. An individual is cycling at a speed of 25 km per hour. He catches his predecessor who had started earlier in two hours. What is the speed of his predecessor who had started 3 hours earlier ?
✅ Correct Answer: (C)
10 kmph
Explanation: The distance covered in two hour,
= 2 × 25 = 50 km
Time taken by first individual = (3h + 2h) = 5h
Then, the speed of predecessor,
= 50/5
= 10 kmph.
Explanation by: Durgesh
The distance covered in two hour,
= 2 × 25 = 50 km
Time taken by first individual = (3h + 2h) = 5h
Then, the speed of predecessor,
= 50/5
= 10 kmph.
= 2 × 25 = 50 km
Time taken by first individual = (3h + 2h) = 5h
Then, the speed of predecessor,
= 50/5
= 10 kmph.
