We know that average speed,
Total distance ÷ total time taken
Given,
distance =30km+20km =50km
time taken = 1hour+1hour= 2hour
so when put the values we get ,
50km÷2hour =25km/hr

Average speed=total distance travelled/total time taken
30km+20km/1hr+1hr
=50/2
25km/hr
so its average speed is 25km/hr
30km+20km/1hr+1hr
=50/2
25km/hr
so its average speed is 25km/hr
