Answer
Answer (as printed):
Explanation
Let the distance be x km. Then, (Time taken to cover x km by cycle) + (Time taken to cover x km by scooter) = 6 hr 30 min ⇒ (Time taken to cover 2x km by cycle) + (Time taken to cover 2x km by scooter) = 13 hrs But, time taken to cover 2x km by cycle = 8 hr 40 min. \ Time taken to cover 2x km by scooter = 13 hrs – 8 hr 40 min = 4 hr 20 min. Hence, required time = 4 hr 20 min.
