When you're new to this, I think it's easiest to do step by step 60 km/hr = 60,000 m/hr, because 1 km = 1,000 m = 60,000/60 m/min, because 1 hour = 60 minutes = 1,000 m/min = 1,000/60 m/sec, because 1 minute = 60 seconds = .... m/sec

60 * 1000/3600

You can multiply 60 Km/h by 5/18 to convert into m/s

4. JamesJ

Yes ... now explain why your methods work. We don't like black boxes.

5. arcticf0x

oh 1KM = 1000m, and 1hr = 3600 seconds I hope that makes it clear

6. kylie0107

I got 16.67 m/s.

7. ash2326

it's correct

8. kylie0107

Thanks for your help!

9. ash2326

Kylie did you get why i multiplied by 5/18?

10. kylie0107

No I didn't do it that way. Where did that come from?

11. ash2326

we have KM/hour 1 KM=1000 m 1 hour= 3600 seconds so 1 KM/hour= 1000m/3600 seconds or 1KM/hour= 10/36 m/sec or 1 km/hour= 5/18 m/sec so to convert km/hour into m/s , multiply by 5/18

12. kylie0107

I got it. thanks I didn't break it all the way down.

i think this way is conveniece $60(km/h)\times(1h/3600s)\times(1000m/1km)$
