All members of our painting team paint at the same rate. If $20$ members can paint a $2000$ square foot wall in $35$ minutes, then how long would it take the $20$ members to paint a $5000$ square foot wall, in minutes?

35   / 2000  =   x /  5000           where x is the  number  of  minutes we are looking for

 

Cross-multiply

 

35 * 5000 =  2000 * x            divide both sides by 1000

 

35 * 5  = 2 * x

 

175  = 2x

 

x = 175 /  2    =    87.5  minutes
