Question

the kids have driven 90 km east at a velocity of 30 km/h. ? how long have they been driving for? 〇 270 h 〇 270 km/h east 〇 0 333 h 〇 0.333 km/h east 〇 3 h 〇 3 m east

Explanation:

Step1: Recall time-velocity-distance formula

Time is distance divided by velocity, so $t = \frac{d}{v}$

Step2: Substitute given values

$d=90\ \text{km}$, $v=30\ \text{km/h}$, so $t = \frac{90}{30}$

Step3: Calculate the result

$t = 3\ \text{h}$

Answer:

3 h
