Sandra orders two trucks of water for her pool. The first truck begins filling the pool at a rate of 60 gallons per minute. The second truck arrives 35 minutes later and starts filling the pool at a rate of 80 gallons per minute. Sandra's pool holds 4,200 gallons of water. The equation 60+80(−35)=4,200 models this situation. How many minutes, m, will it take for both trucks to fill Sandra's pool?
