Question

Plane A has just 1 ton of fuel left and has requested plane B to refuel it. Plane B has 21 tons of fuel. Fuel transfer happens at the rate of 1 ton per minute. Use this information as you work through the activity and find how long it will take to refuel plane A until both planes have the same amount of fuel.

Answer 1

Answer:

10 minutes

Step-by-step explanation:

Plane A = 1 ton of fuel left

Plane B = 21 tons of fuel Left

Fuel transfer = 1 ton per minute

In order for them to have the same amount of fuel,

We add up the fuel left in Plane A and Plane B

= 21 + 1 = 22 tons

This means each plane will equally have 11 tons

How long it will take to refuel plane A until both planes have the same amount of fuel is calculated as:

Plane B will transfer 10 tons of fuel to Plane A which would give plan A a total of 11 tons.

Since transfer rate = 1 ton per minute

= 1 ton = 1 minute

10 tons = 10 minutes.

Therefore, it will take 10 minutes to refuel plane A until both planes have the same amount of fuel.
