Detailed Solution

Concept- Converting distance by using the formula ,

speed = \frac{distance}{time}

, 1 km =1000m
Given, distance = 600m, time = 5minutes

x km = 600 m

x = \frac{600}{1000} km

x = 0.6 km

Converting time,

5 minute in hour

y = \frac{5}{60} h

y = 0.083 h

speed = \frac{distance}{time}

= \frac{0.6}{0.083}

= \frac{(6 \times 1000)}{83 \times 10}

= \frac{6000}{830}

= \frac{600}{83}

= 7.2 \frac{km}{h}

Hence, the correct option is 2.
