a boat can travel 339 kilometers on 113 liters of gasoline. How much gasoline will it need to go 156 kilometers?

339/113 = 3 km per liter

156 * 3 = _____ liters

468

To find out how much gasoline the boat will need to travel 156 kilometers, we can set up a proportion using the given information.

We are given that the boat can travel 339 kilometers on 113 liters of gasoline. Let's call the unknown amount of gasoline needed for 156 kilometers as 'x' liters.

We can set up the following proportion:

339 km / 113 L = 156 km / x

To solve this proportion, we can cross-multiply:

339 km * x = 113 L * 156 km

339x = 17628

To isolate 'x', we divide both sides of the equation by 339:

x = 17628 / 339

Calculating this, we find that x is approximately 52 liters.

Therefore, the boat will need approximately 52 liters of gasoline to travel 156 kilometers.
