To calculate the number of tanks of gas required to travel 735 miles, we divide the total distance by the fuel efficiency, using the following formula:
Number of tanks = Total distance / Fuel efficiency
Number of tanks = 735 miles / 19 MPG
Number of tanks ≈ 38.68
Based on this calculation, it would approximately take 39 tanks of gas to travel 735 miles in a GMC Canyon truck. These figures are estimates and actual fuel consumption may vary, so it's always a good idea to monitor your fuel gauge and plan accordingly during long road trips.
