To find how long it will take to fill the tank, you can use the idea that every 30 seconds will get you one gallon closer to being full.
This means to fill 50 gallons, you will need 50 groups of 30 seconds.
50 x 30 = 1500 seconds
1500/60 = 25 minutes.
It will take 25 minutes.
You could also think of it as filling 2 gallons every minute. It would take 25 of these.

A ratio shows us the number of times a number contains another number. The amount of time needed to fill the empty tank is 1500 seconds.
What is a Ratio?
A ratio shows us the number of times a number contains another number.
Given the truck's gas tank holds 50 gallons of gas. Also, one gallon takes 30 seconds to pump. Therefore, the ratio of the gas-filled to time can be written as,
Amount of gas/ Time taken = 1 gallon/30 seconds
Now it is needed to fill the empty tank, therefore, the time needed will be,
50 gallons/Time needed = 1 gallon/30 seconds
50 × 30 seconds = Time
Time = 1500 seconds
Time = 1500/60 minutes = 25 minutes
Hence, the amount of time needed to fill the empty tank is 1500 seconds or 25 minutes.
