A train leaves at 15.42 and arrives at its destination at 16.56.

If the train travelled 103 km, what was it's average speed in km/h?
Give your answer rounded to 1 dp.

Answer 1

90/1.5=60 mph

Explanation:

I assume that the train is traveling at constant speed.

Between 12:45 pm and 2:15 pm the train has traveled 180-90=90 miles. So 90 miles in 1.5 hours which means that its speed is 90/1.5=60 mph

Answer 2

284.2 KM/HR

Explanation:

16:56

-15:42=1:24

S=D/T

S=103 km/ 7/5 hr

S=284.2 KM/HR
