# What is the speed for a car that went a distance of 125 kilometers in 2 hours time?

May 1, 2018

Given,

$d = 125 \text{km" * (10^3"m")/"km" approx 1.25*10^5"m}$

$t = 2 \text{h" * (3600"s")/"h" approx 7.2*10^3"s}$

Recall,

$\overline{s} = \frac{d}{t}$

Hence,

bars = d/t approx (17.4"m")/"s"

is the average speed of the car.

To calculate the velocity, you would need to provide us with the displacement of the car.
