Felix and Markus want to drive a 60km long route in a maximum of 3 hours. After 40 minutes you do the first time check. How long do you actually need to cover the 60km?
In 3 hrs, distance covered = 60 km
In 180 min, distance covered = 60 km
In 40 min, distance covered
= 60/180 * 40
= 13.33 km
Remaining distance
= 60 - 13.33
= 46.67 km
