Answer:
the total distance walked is 20 km
Step-by-step explanation:
The computation of the total distance he walked is shown below:
Let us assume the total distance walked be d
Now the total time would be
Total time = (d ÷ 2) ÷ 8 + (d ÷ 2) ÷ 5 = 3.25
d ÷ 16 + d ÷ 10 = 3.25
(5d + 8d) ÷ 80=3.25
13d = 260
d = 20 km
Hence, the total distance walked is 20 km
