Two people start at the same place and walk around a circular lake in opposite directions. One walks with an angular speed of 1.10 10-3 rad/s, while the other has an angular speed of 3.90 10-3 rad/s. How long will it be before they meet?

The drawing shows a version of the loop-the-loop trick for a small car. If the car is given an initial speed of 4.5 m/s, what is the largest value that the radius r can have if the car is to remain in contact with the circular track at all times?

I think what she is trying to say is, 3m=8m because you have to divide 3m by 8m.

math question.
are all whole numbers real numbers?

Math.. 3rd time posting /: HELP PLEASE!
All the whole numbers are rational because they can be written as a fraction, and irrational are the ones that can't be written as fractions. I understand that part.

I don't understand how to do it, that's the thing I know that 8 is a whole number, and that the square root of four is 2, and that's a whole number, and the aquare root of 49 is 7, that's a whole number too, and -3 is an interger.
