Question

Seema is travelling to Australia. She travels a distance of 4,500 km by plane to Dubai and then another 11,700 km to Melbourne. Both planes fly at an average speed of 1,100 kmh-1.
What is her total flight time in hours and minutes, to the nearest minute?

Answer 1

Add the two trips together for total Km’s:

4500 + 11700 = 16,200 km.

divide total km by speed:

16,200 / 1,100 = 14.727272 hours

0.727272 x 60 minutes per hour = 43.636363 minutes, round up to 44 minutes

total time: 14 hours and 44 minutes
