O. Rajani can ride her skateboard 2 miles in 10 minutes. How many miles can she ride her skateboard in 1.5 hours? A 9 mi C 15 mi 12 mi D 18 mi

So there are 60 minutes in an hour, so we convert. Then we find out we have 90 minutes so we do 2×9 so the answer is 18 miles

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
