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 =
`(displacement)/(time)`

Displacement = velocity x time

Input the parameters:

8 = 3.8 x time

Time =
`(8)/(3.8)` = 2.1s

The time taken is 2.1s
