84km in Ihr 20mins. Find
His speed average find-​

Answer 1

1.05km/min

Explanation:

`Distance = 84 km\\\\Time = 1hr 20 min= 80minuttes\\\\Average \: Speed = (Distance)/(Time) \\\\A.S =(84)/(80) \\\\A.S = 1.05km/min`

Answer 2

Given:

• Distance = 84km
• Time = 1hr20mins

Find:

• Average speed of man.

Solution:

we, know that

➺ Average Speed = Total Distance/Total Time taken

where,

• Total Distance = 84km = 84000m
• Total time = 1hr20mins = 4800sec

♛ Substituting these values ♛

◗Average Speed = Distance/Time

◗Average Speed = 84000/4800

◗Average Speed = 840/48

◗Average Speed = 70/4

◗Average Speed = 17.5m/s

Hence, Average Speed of the man is 17.5m/s
