Question

Convert 25 m/sec into Km/h​

Answer 1

Explanation:

$\huge{ 25 \: m/s = \frac{ 25 \times \frac{1}{1000} }{ \frac{1}{3600} }} \\ \huge{= \frac{25}{1000} \times \frac{3600}{1}} \\ \huge{= \frac{25 \times 36}{10}} \\ \huge{ = \frac{5 \times 36}{2} } \\ \huge{= 5 \times 18} \\ \huge{= 90 \: km/hr}$

Answer 2

Answer:

is this very simple ☺️ 1 km =1000m and 1 hour=3600 seconds so we can do 3600÷1000=18÷5
