Question

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. How fast did he ride in miles per minute?

Answer 1

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
