For every 1 YARD, that would equal 0.9144 METERS. 
In every 1 METER that would equal 1.094. I rounded that to make it shorter, the non-rounded number would be 1.0936133.
As you should know a minute is 60 seconds and a hour is 60 minutes. 
If you were to convert 7 meters per minute to yards per hour it would be 459.317585. 
Now, your question does not say to round but, I will do it anyways. Most problems should be rounded unless specifically stated not to. 
Rounded that would be 459.32; I rounded to the nearest hundredth. 
I hope this helps!!
