Mr. Dali’s car uses 3/4 gallons of gas each time he drives to work. If his gas tank
holds exactly 9 gallons of gas, how many tanks of gas does he need to make 18 trips to work?
18trips * 3/4 gal/trip = 54/4 = 13 1/2 gallons
so, what do you think?
hmmm .. how does he get home?
Well, if Mr. Dali's car uses 3/4 gallons of gas per trip, and he wants to make 18 trips, we can calculate how much gas he needs in total.
So, 3/4 gallons per trip times 18 trips would give us 13.5 gallons of gas.
But, since his gas tank can only hold 9 gallons, it looks like he's going to need...wait for it...1.5 tanks of gas! Maybe he can borrow a friend's car for that extra half tank.
To find the number of tanks of gas Mr. Dali needs to make 18 trips to work, we need to divide the total number of trips by the number of trips he can make with one tank of gas.
Mr. Dali's car uses 3/4 gallons of gas each time he drives to work, and his gas tank holds exactly 9 gallons of gas.
Thus, the number of trips he can make with one tank of gas is: 9 gallons / (3/4 gallons per trip) = 9 / (3/4) = 9 * (4/3) = 36/3 = 12 trips per tank of gas.
Therefore, to make 18 trips, Mr. Dali needs: 18 trips / 12 trips per tank = 1.5 tanks of gas.
So, Mr. Dali needs 1.5 tanks of gas to make 18 trips to work.
To find out how many tanks of gas Mr. Dali needs to make 18 trips to work, we need to do a few calculations.
First, let's find out how much gas he uses per trip. Mr. Dali's car uses 3/4 gallons of gas each time he drives to work.
To calculate the total gas used for 18 trips, we can multiply the gas used per trip by the number of trips: (3/4) * 18 = 13.5 gallons.
Next, we need to calculate how many tanks of gas are needed to provide 13.5 gallons. We know that Mr. Dali's gas tank holds exactly 9 gallons of gas.
To find out how many tanks of gas are needed, we can divide the total gas used by the gas tank capacity: 13.5 / 9 = 1.5 tanks.
Since we cannot have partial tanks of gas, Mr. Dali will need to purchase 2 tanks of gas to make 18 trips to work.
