Question

Could any of u help me with these question. Its 8th grade science i need help with it

A yacht sailing to the east at a constant velocity took 0.7hours to sail 70kilometers. What was the yacht's velocity?

Answer 1

v = 100 [km/h]

Step-by-step explanation:

To solve this problem we must identify that the movement is at constant speed, that is, there is no acceleration, therefore we must use the following expression for Speed, which relates is displacement with time.

v = d/t

where:

v = velocity [km/h]

d = displacement = 70 [km]

t = time = 0.7 [h]

v = 70/0.7 = 100 [km/h]
