A man takes 6 hours 30 minutes in going by cycle and coming back by scooter. He would have lost 2 hours 10 minutes by going on cycle both ways. How long would it take him to go by scooter both ways?

Going by scooter both ways takes 4 hours 20 minutes.

Cycle one way + scooter one way = 6 hr 30 min.

Cycle both ways = 6 hr 30 min + 2 hr 10 min = 8 hr 40 min.

So cycle one way = 4 hr 20 min.

Scooter one way = 6 hr 30 min - 4 hr 20 min = 2 hr 10 min, so both ways = 4 hr 20 min.
