Answer:
$125 in a year ($2,625 total)
Step-by-step explanation:
We know that a percentage is out of 100 so we set up a proportion:
5/100 = x/2500
When we crossmultiply we get 12,500 then we divide by 100, getting us 125.
If t varies inversely with the speed, the formula for that is 
. If t = 2 and r = 40, then we can solve for k, the constant of variation. Multiply both sides by 40 to get k = 80. Now we need to find the value for t when r = 45. Using the k value we just solved for, we will fill in the equation as 
for a t value of about 1.78 hours
