Answer:

Step-by-step explanation:
we know that
Hunter was biking for 2 hours 20 minutes and covered 35 miles
so
using proportion
Find out how long would it take him to cover 17 miles on this bike
Remember that
1 h=60 min
2 h 20 min=2(60)+20=140 min
Let
x -----> the time to cover 17 miles

therefore

Answer:
c.
Step-by-step explanation:
Hello,
Your sequence is arithmetic.
10.5-9=1.5
9-7.5=1.5
7.5-6=1.5
6-4.5=3
4.5-3=1.5
3-1.5=1.5
1.5-1.5=0
...
f(x)=f(n-1)-1.5 is the iterative rule.
f(1)=10.5
f(2)=10.5-1.5=9
f(3)=10.5-2*1.5=7.5
f(4)=10.5-3*1.5=6
...
f(n)=10.5-1.5*(n-1) is the general form.
30.6
I do not have an in depth explanation, but this is for the people who are having trouble finding it, gl!
