Question

Mario walked at a rate of 2/3 miles every 10 minutes what is his unit rate every mile per hour

Answer 1

Mario's unit rate is given by 900 miles/hour.

Explanation:

We have been given that Mario walked at a rate of 2/3 miles every 10 minutes.

We have the relation between speed, time and distance, which is given by

$\text{Speed}= \frac{\text{Distance}}{\text{Time}}$

We have,

Distance = $\frac{2}{3} \text{ miles}$

Time = 10 minutes

On substituting these values in the above formula, we get

$\text{Speed} = \frac{2/3}{10}\\\\ \text{Speed} =\frac{2}{10\cdot 3}\\\\ \text{Speed} =[tex]\frac{1}{15}$ \text{ miles/min}[/tex]

We have to find the unit rate in mile per hour, so we need to multiply it by 60

Thus, unit rate is given by

$\frac{1}{15} \times 60\\ = 4 \text{ miles/hour}$
