Answer:
Average speed = 48 km/h
Explanation:
Total distance travelled = Distance travelled to reach the final point + distance travelled to reach the initial point
According to the question;
Distance travelled to reach the final point = 120 km
Distance travelled to reach the initial point = 120 km
So,
Total distance travelled = 120 km + 120 km = 240 km
Time taken to reach final point =
In the question it is given that;
Speed to reach the final point = 40 km/h
So,
Time taken to reach final point =
Time taken to reach final point = 3 hr
Time taken to reach final point =
In the question it is given that;
Speed to reach the initial point = 60 km/hSo,
So,
Time taken to reach final point =
Time taken to reach final point = 2 hr
