Find the total distance he travels,

D=5%2A6%2B4%2A12=30%2B48=78

Find the total time it takes,

T=6%2B12=18

Divide to find the average speed,

S=D%2FT=78%2F18=13%2F3kph

Answer 2

Answer:

• Answer is 14.67

Step-by-step explanation:

1)speed=6km/h

Time=5hours

so,

distance=speed*time

distance=6*5=30km

2)speed=4km/hr

Time=10hours

distance=4*10km=40km

now,

average speed=Total distance/Total time taken

so,

Total distace=40+30km=70km

total time=10+5hrs=15hrs

So,

Average speed=70/15km/hr=4.67km/hr

Here's you answer..
