Answer:
Total distance: 55km, Time traveled: 1 hour 30 mins, Average Speed: 46.6 km/h.
Explanation:
If the car travels 30 km/h for half an hour, then that's equal to a distance of 30/2. Then, 40 km/h for one hour is simply 40 km. 40+15 =55. The time traveled is addition on 30 mins and one hour, giving you 1 hour 30 mins. Finally for average speed:
40 km + 30 km = 70 km.
30 mins = 1 hour = 1.5 hours
70/1.5 = 46.67 km/h
