Show answer & explanation
Correct answer: A
Let the actual distance be x km.
Time taken at 10 km/h = x/10 hours.
In the same time at 14 km/h the distance covered = 14*(x/10) = 1.4x km.
This distance is 20 km more than the actual distance, so 1.4x = x + 20.
Solve: 1.4x - x = 20 ⇒ 0.4x = 20 ⇒ x = 50.
Therefore, the actual distance travelled is 50 km.
