Answer:

5km/hr

Step-by-step explanation:

Given

Distance = 3km and 2km

Time = 30 mins, 15 mins, 15 mins

Required

Determine the average speed

To answer this, we need to determine the total distance.

Distance =3km + 2km = 5km

Then, we calculate the total time

Time = 30 mins + 15 mins + 15 mins = 1 hr

Next, we can now determine the average speed using:

Average Speed = Total Distance/Total Time

Average Speed = 5km/1 hr

Average Speed = 5km/hr
