Question

A train leaves at 08:36 and arrives at 10:57. It travelled at an average speed of 85 km/h.

How far did it travel? Give your answer in km to 1DP.

Answer 1

199.8 km to the 1 decimal point

Explanation:

8:36 to 9:00 is 24 min

9:00 to 10:00 is 60 min

10:00 to 10:57 is 57 min

That's a total of 24 + 60 + 57 = 141 min = 141/60 hr.

d = rt = 141/60(85) = 199.8 km to the 1 decimal point
