28 km/h ;
If he traveled back with an average of 35km/h and did it in 4 hours then the distance he traveled is 35 x 4 = 140 km
The trip there took him 5 hours so his average speed = 140/5 average speed of trip there=28km/h
Jose's average speed for the trip to the town hall was calculated to be 28 km/h. This was determined by first finding the distance to the town hall using the return trip's speed and time. Then, this distance was divided by the time taken for the trip to find the average speed.
