Question

on average, a commercial airplane burns about 3.9 × 10³ ml of gasoline per second. there can be as many as 5.1 × 10³ airplanes in the air in the united states at any given time. about how many milliliters of gasoline are burned per minute by commercial airplanes in flight in the united states? enter your answer in the box. 1.2 x 10 __ ml

Answer 1

The required answer is
`1.2* 10^9` ml/min.

Explanation:

Consider the provided information.

On average, a commercial airplane burns about 3.9 × 10³ ml of gasoline per second.

In one minutes a commercial airplane burns about = 60×3.9×10³ ml of gasoline

`60* 3.9*10^3 ml =2.34* 10^5`

There can be as many as 5.1 × 10³ airplanes in the air in the united states at any given time.

Now multiply
`2.34* 10^5` with 5.1 × 10³.

`2.34*5.1* 10^(5+3)`

`2.34*5.1* 10^8`

`11.934* 10^8`

`1.2* 10^9` approximately

Hence, the required answer is
`1.2* 10^9` ml/min.

Answer 2

We use the given data above to calculate the volume of gasoline that is being burned per minute by commercial airplanes.

Amount burned of 1 commercial airplane = 3.9 × 10³ ml of gasoline per second
Number of airplanes = 5.1 × 10³ airplanes

We calculate as follows:

3.9 × 10³ ml of gasoline per second / 1 airplane (5.1 × 10³ airplanes)(60 second / 1 min ) = 1.2 x 10^9 mL / min
