Convert the following speeds into $$km/h:$$
$$1.5\ m/sec$$

$$15\ m/sec$$
$$1\ m=\dfrac{1}{1000}\ km$$
$$1\ sec=\dfrac{1}{3600}\ hours$$
$$\dfrac{1\ m}{s}=\dfrac{1}{1000} \div \dfrac{1}{3600}=\dfrac{3600}{1000}$$
$$=\dfrac{18}{5}\ km/h$$
$$\therefore 15\ m/s=15 \times \dfrac{18}{5}\ km/h=54\ km/h$$

Convert the following speeds into $$km/h:$$$$1.5\ m/sec$$

$$15\ m/sec$$$$1\ m=\dfrac{1}{1000}\ km$$$$1\ sec=\dfrac{1}{3600}\ hours$$$$\dfrac{1\ m}{s}=\dfrac{1}{1000} \div \dfrac{1}{3600}=\dfrac{3600}{1000}$$$$=\dfrac{18}{5}\ km/h$$$$\therefore 15\ m/s=15 \times \dfrac{18}{5}\ km/h=54\ km/h$$
