1. a car travels a distance of 120 kilometers in 2 hours. what is its speed?

Explanation:

Step1: Recall speed - distance - time formula

The formula for speed is $v=\frac{d}{t}$, where $v$ is speed, $d$ is distance, and $t$ is time.

Step2: Substitute given values

Here, $d = 120$ kilometers and $t=2$ hours. So $v=\frac{120}{2}$.

Step3: Calculate the speed

$v = 60$ kilometers per hour.

Answer:

60 kilometers per hour
