Machine puts tar on a road at the ratio of 4 meters in 5 minutes how long does it take to cover 1 km?

If each 4m section takes 5mins, in 1km = 1000m there are 1000/4 = 250 of these sections.
Each section takes 5 mins to tar, so 250 of them take 250 x 5 = 1250 mins.
1250 mins = 20 x 60 + 50 mins = 20 hours 50 mins.
