Question

Question 4 How much time does it take to walk 8 km north at a velocity of 3.8 km/h?​

Answer 1

Given parameters:

Displacement = 8km

Velocity  = 3.8km/h

Unknown:

time  = ?

Solution:

Velocity is displacement divided by time.

  Velocity  = $\frac{displacement}{time}$  

      Displacement  = velocity x time

Input the parameters:

              8  = 3.8  x time

 Time  = $\frac{8}{3.8}$   = 2.1s

The time taken is 2.1s
