ANSWER:
a. 50.53 km/h
b. 32.53 km/h (in the direction of 25˚ S of E)
c. 4.27 km/h
d. 0 km/h
STEP-BY-STEP EXPLANATION:
a.
We have that the speed is given by the following formula:
We know that the equivalence between minutes and hours is that 60 minutes equals 1 hour, therefore:
b.
The velocity is given by the following formula
c.
The total distance traveled would then be two 16 kilometers, that is 32 km and the time would be 7.5 hours. we replace
d.
Since it starts in the same place that it ends, the displacement is equal to 0, therefore, the velocity is equal to 0 km/h
