25 points if you answer. Martin Rode his bike 3 2/3 miles in 16 1/2 minutes. Assume he wrote the same speed the entire time. Ho

Illusion [34]

Answer:

The speed is 2/9 miles per minute

Step-by-step explanation:

Speed is defined as the distance covered per unit time.

The formula for speed is given by:

$Speed = \frac{distance}{time}$

Let s be the speed, d be the distance and t be the time then

$s = \frac{d}{t}$

Given

$d = 3\frac{2}{3} = \frac{11}{3}\ miles\\t = 16\frac{1}{2} = \frac{33}{2}\ minutes$

The speed will be calculated by dividing the number of miles by minutes

So putting the values in the formula

$s = \frac{\frac{11}{3}}{\frac{33}{2}}\\= \frac{11}{3} * \frac{2}{33}\\=\frac{1}{3} * \frac{2}{3}\\=\frac{2}{9}$

Hence,

The speed is 2/9 miles per minute

Y varies directly with the square x. If y= 27 when x = 3, find y when x = -4

Lana71 [14]

Answer:

y~x²

y/x²= k

27/3²=3

therefore k= 3

y/ -4 = k

y / -4= 3

3y = -4

y = -4
