The second ant is moving at a rate of 8/3 inch per second. The first ant's rate is 2 inches per second, which can be represented as 6/3 per second. 6/3 x 1 = 6/3, and 6/3 x 1/3 = 2/3. 6/3 + 2/3 = 8/3.amirp wrote:Hi guys,
Can anyone tell me what the "Rate" of the 2nd ant is that is heading west?
Is it 7/3 inch per sec or 8/3 inch per second and why?
thanks
You don't really need to deal with fractions to answer this, though; you can figure out pretty easily that the first ant moves 12 inches in 6 seconds, and 12 x 4/3 = 16. The legs of the triangle are therefore 12 and 16, and the hypotenuse is 20 inches, or 1 2/3 (1.67) feet.
