Question

a toy car moved along a 1.2 km track in 6 min. find the speed of the toy car. 200 m/h 12 km/h 1.2 m/min 0.2 km/h

Explanation:

Step1: Convert time to hours

Since 1 hour = 60 minutes, 6 min=$\frac{6}{60}=0.1$ h.

Step2: Use speed formula

The speed formula is $v = \frac{s}{t}$, where $s$ is distance and $t$ is time. Given $s = 1.2$ km and $t=0.1$ h, then $v=\frac{1.2}{0.1}=12$ km/h.

Answer:

B. 12 km/h
