The speed of sound is 340 / s, converted into km / h, how to convert? Please write down the conversion process
340m/s=（340÷1000）km/(1÷3600）h=1224km/h
What is the conversion from 13m / s to km / h
13m / S = 13 × 60m / min = 13 × 60 × 60m / h = 1.3 × 6 × 6km / h = 46.8km/h
How to convert minutes into seconds
Give me a formula
1 minute 60 seconds, 5 minutes 60 * 5 = 300 seconds
