16.62 miles is the distance the runner can run in 1 3/4

Using the formula d=rt we multiply 9.5 (rate) times 1.75(time).

We solve and then we get the result 16.62.

9.5*1.75=16.62<---- <em><u>Result</u></em>

Hope this helps!

d=rt

r = 9  1/2  as an improper fraction   (2*9 +1)/2 = 19/2

t = 1 3/4  as an improper fraction (4*1+3)/4 =7/4

d=rt

d = 19/2* 7/4 = 133/8

8 goes into 133 16 times with 5 left over

16 5/8 miles

A toy company is making a miniature model of a dump truck. The steering wheel on the toy car that is 0.6 cm corresponds to the s
pentagon [3]
I used the 55.2 and the 0.6 to find a ratio of 92:1, so for every cm of toy car steering wheel there are 92 cm of real truck steering wheel. so using this ratio i times the 3.5cm of the toy car windshield by the 92, this gave me the answer of 322cm, which theoretically is the answer of this equation. 322cm.
