Answer:
(A). The rabbit travel the distance 138 m.
(B). The average speed of the hiker for the entire trip is 7.2 km/h.
Explanation:
Given that,
Speed = 12.0 m
Time = 11.5 second
(A). We need to calculate the distance
Using formula of distance
[tex]d=v\times t[/tex]
[tex]d =12.0\times11.5[/tex]
[tex]d=138\ m[/tex]
The rabbit travel the distance 138 m.
(B). Given that,
Distance = 5.10 km
Time = 1 hours
Distance 16.5 km
Time = 2 hours
We need to calculate the average speed of the hiker for the entire trip
Using formula of average speed
[tex]v=\dfrac{D}{T}[/tex]
Where, D = Total distance
T = Total time
Put the value into formula
[tex]v=\dfrac{5.10+16.5}{1+2}[/tex]
[tex]v=7.2\ km/h[/tex]
The average speed of the hiker for the entire trip is 7.2 km/h.
Hence, This is the required solution.
