Question

Mario walked at a rate of 5/6 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

speed = distance/Time

we have,

distance = 2/3 miles

Time = 10 minutes

On substituting these values in above formula, we got

speed 2/3 /10

speed 2/10.3

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

1/15 X 60

= 4 miles/hour

Answer 2

Mario's unit rate is 5/1

Explanation:

We know that Mario walks 5/6 miles per 10 minutes.

We need to find out how many miles Mario walks in 60 minutes (1 hour).

10 * 6 = 60. Which means that we must multiply 5/6 by 6.

`(5)/(6) *(6)/(1) = \frac{30}6`

30/6 = 5

Mario walks 5 miles per hour.

To put this in to a unit rate we must put this is a fraction:

`(Miles)/(Hour)`

Substitute:

5/1
