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
