Answer:

= 0.38 m/s

Step-by-step explanation:

â–ªTotal distance = 800 m

5 min = 100 m

â–ªRemaining distance = 800 - 100 = 700 m

20 min = 700 m

â–ªTotal time taken = 20 + 10 + 5 = 35 min

If 1 min = 60 sec

What about 35 min = ?

= 35 x 60

= 2100 sec

▪Average speed = TD ÷ TT

= 800 ÷ 2100

= 0.38 m/s
