givens:
unknown:
equation:
substitute
solve:

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

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.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
