The graphing calculator screen displays an area of 96 square units After you zoom out once, the area is 384 square units. After
you zoom out a second time, the area is 1536 square units.
Determine the formula for this sequence.
Answer here:

0.7 of an hour

Step-by-step explanation:

Average Speed tells the rate at which the object is traveling his whole journey.

Let the distance of Irina's home to her work be "x" miles.

Also, the time is taken for traveling from Irina's home to her work be "t" hours.

Then, we can write average speed of 16 miles per hour as                                                                   →      (1)

Also, Average speed of car is 27 miles per hours in 0.4 of an hour, which can be written as                        →        (2)

∴ Distance(x) = 0.4 × 27 = 10.8 miles

Using this value of x in equation (1)

We get time (t) = 10.8 ÷ 16 = 0.675 ≈ 0.7 of an hour

Hence, last option is true.
