Thread: Measure of Degree Wordproblem...

Idk what steps to follow thru with! The majority of my tests will include questions like this... can you please list steps or procedures?

A tower resturant in Sydney, Australia, is 300 meters above sea level and provides a 360 degree panoramic view of the city as it rotates every 70 minutes. A tower resturant in San Antonio TX is 750 ft tall. It revolves at a rate of one revolution per hour.

a. In a day, how many more revolutions does the resturant in San Antonio make than the one in Sydney?

b. In a week, how many more degrees does a speck of dirt on a window of the restuarnt in San Antonio revolve than a speck of dirt on the window of the resturant in Sydney?

Please help! I have no idea how to do these kinds of problems and my test is monday.

The tower in Sydney revolves once every 7/6 hours

Since there are 24 hours in a day, then it revolves 24/(7/6)=20.571 revolutions in a day.

It is easy enough to tell how many times the tower in San Antonio revolves in a day since it is once every hour.

Subtract the two values to find the difference.

As for part 2, there are 360 degrees in a circle (assuming you are using degrees and not radians). The Sydney tower revolves 20.571 times in a day so that is 144 times in a week. That is 360*144=51,840 degrees in a week.

Now, can you find how many degrees the San Antonio tower turns in a week?. Then subtract the two to fins the difference.

Ok I think I get it. You got [ 1.17 ] or 7 / 6 by diving 70 / 60.

And then you found the angle measure by doing mintues times hours in a day (7 / 6)= 20.571

And just subtract the Sydney distance with San Antonio's which is 24.00? Since its only (one hour)(hours in a day)

Which gave me: a 3.43 difference

And on the second part:

You got 144 times in a day by multiplying the sydney revolutions with how many days a week there are, soooo you got 51,840 degrees a week by multiplying it with 360 degrees.


And San Antonio's would be (360)(168)= 60,480 degrees a week

Correct?

Correct
