Answer:
15km/hr
Explanation:
The average speed for the entire trip is the sum of the total distance traveled divided by the total time of the trip.
Total time = 4hr
distance for the first 3hrs = 50km
distance for the last 1hr = 10km
Total distance = 50km + 10km = 60km
Now;
Average speed =
Insert the parameters and solve;
Average speed =
= 15km/hr
