If you were travelling at 25 kmh, every hour means you have travelled 25 kilometres. Therefore it would take you 2 hours to travel 50 kilometres.
40 minutes is the time taken to travel 30 miles (48.3 kilometres) at an average speed of 45 miles per hour.
Dividing distance by speed gives 160/80 = 2. Therefore, it would take 2 hours to travel 160 kilometres at 80 miles per hour.
15 miles is equal to 15 x 1.609344 = 24.14016 kilometres. Dividing 400 kilometres by 24.14016 kilometres per hour. and rounded to two decimal places, gives 400/24.14016 = 16.57 hours or approximately 16 hours 34 minutes.
