Answer: 15 minutes
Step-by-step explanation:
Given : Tonya runs 8 kilometres in 60 minutes.
We know that the rate of distance covered with respect to time is given by :-
Rate of distance covered with respect to time for Tony=kilometers per minute
Let t be the time taken by her to run 2 kilometers.
Then, Rate of distance covered with respect to time =
If rate remains the same, then we have
Hence, it would take 15 minutes to run 2 kilometers.
if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min) × $0.35
Here x will represent the number of minutes.
so if 0 < x ≤ 450, y = $60.
And,
if 450 < x ; y = $60 + (x - 450min) × $0.35
where we use (x - 450) ×$0.35 since any minute after the 450 minute mark is considered an extra time.

Answer: if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
Step-by-step explanation:
Here x will represent the number of minutes.
with $60 you have 450 minutes, and you must pay 60 regardless of how much minutes you use.
so if 0 < x ≤ 450, y = $60.
now, if you call for more than 450 minutes, you get an additional of $0.35 per minute, then we have:
if 450 < x ; y = $60 + (x - 450min)*$0.35
where we use (x - 450)*$0.35 because any minute after the 450 minute mark is considerated an additional time.
So our piecewise function is:
if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
