Question

man walks from his home to a post office at a distance of 500 metre in 20 minutes he then returns to his home in 25 minutes find the average speed of man​

Answer 1

Answer:

Step-by-step explanation:

First we have to change 20 min into seconds,i.e.

20 \times 60

1200 seconds

Now we have to change 0.5km in metres,i.e.

0.5 \times 1000

500m

also 25 minutes into seconds =1500 seconds

now, Average speed is

Total distance travelled/total time taken

so,

500 + 500 \div 1500 + 1200

0.3m/s
