Since you've not provided anything about the direction of
moving, but the average speed, we can determine the time of
travel:
We'll recall the formula that gives the time when
we know the distance and the average speed:
total time =
total distance walked/v av.
total time =
900Km/5Km/h
total time = 180
hours
If the person walks 5Km/h, 10h/day,
we'll
get:
5km................1h
x
km...............10h
We'll apply the rule of 3, to get the
number of km traveled in 10 hours.
x = 5*10 =
50Km
The person walks from A to B within
900/50 = 18 days.
To determine the time of
travel if the average speed is of 1.5m/s, we'll convert the 900Km into meters =>
900Km = 900*1000= 9*10^5 m
total time = 9*10^5 m/1.5
m/s
total time =
9*10^6/15
total time =
3*10^6/5
total time = 6*10^5
s
