Answer 1

Answer:

52 km/hr

Explanation:

Answer 2

Answer:

Average speed = total distance/ total time taken

Case 1st

Distance = speed× time

Speed = 40kmph

time = 4 hr

Distance = 40 × 4

Distance = 160 km

Case 2nd

Speed = 60kmph

Time = 6hr

Distance = 60 × 6

Distance = 360 km

Now average speed

Speed =( 160 +360)/4+6

Speed = 520/10

Speed = 52 kmph

Average speed = 52 kmph
