Answer:
4 or 4.75
 or 4.75
Step-by-step explanation:
first we're going to convert the number into improper fractions.
7 =
=  and 2
 and 2 =
= 
For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply  x2, it'll equal the same number.
x2, it'll equal the same number.
So now we have  -
- , 30-11= 19.
, 30-11= 19.
 simplified is, 4
 simplified is, 4 .
. 
As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.
I hope this helps you!

Step-by-step explanation:
 Alr so-
You want first divide 3 by 3/5 since well- the question asks how many does he ride in 3 hours
Of course, you'll get the answer 5
Now you want to grab the 6 miles Jake could ride in 3/5 hours and put it in a new equation.
(you'll also want to take the 5 you got from the last equation)
You want to multiply both 6 and 5 which is 30
BOOM!
IN CONCLUSION-
the answer is 30 miles
