Answer:

70 km/h

Explanation:

The average speed is given by combining the two speeds and dividing them by two

Given

Speed to office as 57 km/h

Speed to house as 83 km/h

The differences in speeds may be due to the terrain of the land

Total speed is 57+83=140 km/h

Average speed is 140/2=70 km/h
