Answer 1

Answer:

we know ,

average speed=total distance traveled/total time taken

total distance= (10+5+15+10)km.=40 km.

total time = (15+15+15+15)min. = 60 min.

  but we have to convert time into hour. so 60 min. = 1 hour

 by putting values in the formula=

=40/1

average speed=40 km/h. ans.
