Question

A pilot was scheduled to depart at 4:00 pm, but due to air traffic, her departure has been delayed by 10 minutes. Air traffic control approved a new flight plan that will allow her to arrive three times faster than she calculated in her original flight plan. Let x represent the time, in minutes, of her original flight. Create an equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination.

Answer 1

Y= X/3 + 10

Explanation:

The initial time of departure = 4.00pm

Her flight was then delayed for 10 minutes

Let the initial flight plan be X

Let the new flight plan be Y

The new flight plan allows her arrive at her destination three times faster. this means Y = (1/3)X

Y = X/3

The equation to know the number of minutes after 4.00pm she will arrive is

1/3 of the initial plan + the 10 minutes of delay

Y = X/3 +10

Answer 2

y = 1/3x + 10

Explanation:

The test doesn't offer the answer with X over 3. These are the answer choices:

y = 1/3x + 10

y = 3x + 10

y = 1/3x - 10

y = 3x - 10
