Answer: in this question the easiest way to find an answer is by cross multiplying ....i hope i am right

Step-by-step explanation:

1 hour=25miles

9hours=x

cross multiply which will give u

1x=25x9

1x=225

x=[tex]\frac{225}{1}[/tex]

x=225miles

hope this helps

OR

1hour= 25miles

9hours=x

so u know in 9hours the miles swam will obviously will be more so if it is more less will divide

which will be=[tex]\frac{9}{1}[/tex]×21 =225 miles

HOPE THIS HELPSSSSSSSSSS!!!!!!!!!!!!!
