Answer 1

Answer:

0.4 km or 400 meters

Step-by-step explanation:

10 minutes = 8 km or 8000 meters

1 min = 800 m

30 seconds = 400 meters

Answer 2

Step-by-step explanation:

I))time taken by man to cover 8 km= 1h 20 minutes = 80 minutes = 4800 s

in 1 s he will cover = 8000/ 4800 = 5/3 m

in 30 s he'll cover = 5/3. x 30 = 50 m

time taken by man to cover 8 km = 80 minutes

time taken by him to cover 1 km = 10 minutes

so time he'll take to cover 6.5 km = 65 minutes = 1 h 5 minutes
