Answer 1

Answer:

3.6 hours

Step-by-step explanation:

I am assuming you mean 9 1/4 miles in exactly ONE hour. If not, just substitute in the correct number of hours.

you set up a ratio

9 1/4 m      1 hour

----------  =  ----------

33 3/10 m           x

cross multiply

9 1/4 * x = 33 3/10 * 1 = 33 3/10

solve for x

x=33 3/10 / 9 1/4

x=3.6
