You can put this solution on YOUR website!
Add their rates of working to get
their rate working together
Edwin's rate: ( 1 pound chopped ) / ( 8 min )
Bella's rate: ( 1 pound chopped ) / (5 min )
Let +t+ = the time in minutes
+1%2F8+%2B+1%2F5+=+1%2Ft+
Multiply both sides by +40t+
+5t+%2B+8t+=+40+
+13t+=+40+
+t+=+3.077+
+.077%2A60+=+4.62+
It will take them 3 hrs and 4.6 minutes working together
