torisob [31]

Answer:

$4.

Step-by-step explanation:

Let us assume that Pete and Teegan each put an amount of $P in a new bank account.

Teegan's account earns 2.75% simple interest and she earned $2.20 in interest after one year.

So, we can write \frac{P \times 2.75}{100} = 2.20

⇒ P = $80

Now, this $80 in Pete's account earns 5% simple interest.

Then after one year Pete will earn as interest \frac{80 \times 5}{100} = 4 Dollars. (Answer)

Two planes are flying towards each other. In 45 minutes, the two planes will be
ELEN [110]

The distance between the two planes will be 800 miles.

It should be noted that the total speed of the two planes will be the sum of their individual speeds. Also, the planes have 1 hour to meet each other.

From the information given, the distance between the planes is 200 miles after they flew for 45 minutes. Therefore, the remaining distance will be:

= 1 hour - 45 minutes = 15 minutes.

The distance between the planes will then be:

= 200/15 × 60

= 200 × 4

= 800 miles

Therefore, the distance between the two planes will be 800 miles.
