A plane takes off at 6:00 am, traveling north at 270 miles per hour. A jet takes off at 7:00 am, traveling north at 460 miles per hour. At what time will the jet overtake the plane? (Round your answer to the nearest minute.)

Answers

Answer:

The jet will overtake the plane at 8:25 am.

Step-by-step explanation:

The distance $D_p$ traveled by the plane after time $t$ since it took off is modeled by the equation

$D_p = 270t$

And the distance $D_j$ traveled by the jet after time $t$ since the plane took off is given modeled by the equation

$D_j =460t-460$ (we set this up such that at $t=1,$ $D_j= 0$ )

Now, the jet will overtake the plane when $D_j> D_p$ :

$460t-460> 270t$

$460t-270t> 460$

$190t>460$

$\boxed{t> 2.42\: hours }$

Which is 2 hours and 25 minutes after 6:00 am, or at 8: 25 am; therefore, the jet will overtake the plane at 8:25 am.

A used book sale charged $7.50 for hardcovers and $1.25 for paperbacks. During the sale, 15 hardcovers were sold and the sale earned $166.25. Write and solve an equation to determine the number of paperbacks, p, that were sold. 20 points i think

Answers

Answer:

43 paperback books

Step-by-step explanation:

7.50(15) + 1.25x = 166.25

112.50 + 1.25x = 166.25

Subtract 112.50 from both sides

(112.50 - 112.50) + 1.25x = (166.25 - 112.50)

1.25x = 53.75

Divide 1.25 from both sides

x = 43
