Answer:

12.4\frac{miles}{hour}

Step-by-step explanation:

we know that

To find the speed divide the total distance by the total time

so

Let

x-----> the total distance in miles

y----> the total time in hours

s----> speed in miles per hours

s=\frac{x}{y}

we have

x=33.48\ miles

y=2.7\ hours

substitute the values

s=\frac{33.48}{2.7}=12.4\frac{miles}{hour}

Parker Middle School's chior needs to raise $480 for an upcoming trip they will take. At their first fundraising project, they r
harkovskaia [24]

The money does the choir still need to raise is $180.

<u>Step-by-step explanation:</u>

The money needed to be raised by the choir for an upcoming trip = $480.

It is given that, the money needed was raised in two fundraising projects.

<u>During the first fundraising project :</u>

The choir raised 25% of the money needed for the trip.

⇒ 25% of 480

⇒ (25/100) × 480

⇒ (1/4) × 480

⇒ 120

Therefore, the first fundraising project raised $120.

<u>During the second fundraising project :</u>

The choir raised 3/8 of the money needed for the trip.

⇒ 3/8 of 480

⇒ (3/8) × 480

⇒ 3 × 60

⇒ 180

Therefore, the second fundraising project raised $180.

<u>To find the money does the choir still need to raise :</u>

You need to find the remaining amount from the 480 after raising money from the two fund raising projects.

For that, find out how much you raised from those fund raising projects and subtract it from the 480.

Money needed = Total money required for the trip - Raised money

⇒ 480 - (120+180)  

⇒ 480 - 300

⇒ 180 dollars.

The money does the choir still need to raise is $180.
