Question

Numericals Express 15ms-1 in kmh-1 Give explanation how it comes??

Answer 1

Answer: 54 km/hr

Explanation:

As we know that if we convert km/hour to m/s then we multiply and divide by 1000m/3600s or 5/18 m/s and if we convert m/s to km/hr we will do vice versa of it. So we will multiply and divide by 18/5 . The answer comes out to be 15*18/5 = 54 km/hr
