Read a distance in kilometres and an average speed in km/h (both may be decimals). Work out how long the trip takes, round it to the nearest whole minute, and print it as <h> h <m> min.
Examples
Input:
150
60
Output:
2 h 30 min
Input:
100
80
Output:
1 h 15 min
Constraints
0 <= distance <= 100000,1 <= speed <= 1000
Goals
- Compute a travel time from distance and speed
- Convert a fractional number of hours into hours and minutes
- Round to the nearest whole minute
