Answer:
Time = 1 h 45 min = 1×60×60 + 45×60 = 3600 + 2700 = 6300 seconds. Because 1 hour = 60 minutes and 1 minute = 60 seconds. Now, Henceforth, the average speed is 1ms-1.
Explanation:
Answer: 36km/h
Total distance covered = 63km
Total time taken = 1h 45 min
Converting 1h 45 min into hour
1h = 60 min
1min = 1/60 h
45min = 45/60
= 3/4h
=1h + 3/4h
= 7/4h
Average speed = Total distance ÷ Total time
= 63 ÷ 7/4
= 63 × 4/7
= 252/7
= 36km/h ans.
