Answer:
1) Givens: time - 1 hr 23 min
Unknown: displacement, velocity
Equation: d = v x t
Substitute: -
Solve: -
2) Givens: velocity - 67 m/s; distance - 550 m
Unknown: time
Equation: t = d/v s
Substitute: t = 550/67 s
Solve: t = 8.21 s
Step-by-step explanation:
The relation between the velocity, displacement, and time is given by the equation,
velocity = displacement / time
Or, displacement of a body is equal to the product of its velocity and time taken to travel the distance.
If there are two knowns in the equation, the unknown can be calculated from the above relation.
