two cars travel in opposite directions, starting from the same place at the same time. One travels at an average rate of 48 miles per hour and the other averaged at 55 miles per hour. in how many hours will the be 618 miles apart?
Answers
so in 1 hour they will be 48+55=103 miles apart how many hours will it be in 618 103 times x hours=618 divide both sides by 103 x=618/103 x=6
the answer is 6 hours

How is the area of a sail related to the weight of the pilot on a hang glider?
Answers
The correct answer is:
The larger the surface area of the sail, the heavier the pilot can be and safely use the glider.
Explanation:
A hang glider must be able to support the weight of the pilot. The air pushing up under the sail (wing) of the glider helps support the weight. The more sail (wing) that you have, the more air pushing up, and the more weight it can hold.
The area of the sail is correlated to the weight of the pilot on the hang glider because the surface area of the sail needs to be able to lift ≤ (greater than or equal to) weight of the pilot.
It takes 45 minutes to bake 2 dozen cupcakes. At this rate, how many hours would it take to bake 8 dozen cupcakes? I need to show all work involved at arriving at the answer.
Answers
First you need to find how many minutes it takes to bake 1 dozen cupcakes. 45/2=22.5 minutes Now you can start finding how many hours it would take to bake 8 dozen. 22.5 * 8 = 180. 180/60=3 Your answer is 3 hours!
well lets make these into fractions:)
2 8 --- -> ---- 45 x
see this is simple now we just have to find x what do we multiply too 2 to get 8? 4 right? so keeping that in mind we do the same thing to the denominator(the 45)
sooooo 45 x 4 = 180 now this is in minuets and since there are 60 minutes in one hour lets divide 180/60 = 3 see how simple this one was? so it would take you three hours to make 8 dozen cupcakes
