Sarah is training for a bike race. she rides her bike 5 3/4 miles in 1/3 hour. what is sarah's rate miles per hour?

Step-by-step explanation:

Sarah's rate is 17 miles per hour.

Step-by-step explanation:

we can use proportion to solve this;

Let x represent sarah's rate miles per hour

5 3/4 miles = 1/3 hour

    x             = 1 hour

cross-multiply

5 3/4  = 1/3 x

but 5 3/4 =

 =  

cross- multiply

4x = 23× 3

4x =69

Divide both-side of the equation by 4

=

(On the left-hand side of the equation, 4 at the numerator will cancel-out 4 at the denominator while on the right-side of the equation 69 will be divided by 4)

x  =  17 miles

Therefore Sarah's rate is 17 miles per hour.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
