Answer:

Let the distance covered during the first half journey be x.

Speed during first half = 35 km/h

Time taken = x/35

Distance covered during return journey is also x.

Speed during return journey = 25 km/h

Time taken = x/35

Average speed = 2x/x/35+x/25

Average speed = 175*2/12

Average speed = 29.16 km/h

Hence, the average speed for the entire journey is 29.16 km/h
