Hello Cassidy,
To solve this problem, you could use a proportion to solve for your question. I have attached the work as well. On the top of your fractions, can be the money. On the bottom is the minutes. Note: these can be interchangeable, as long as all your numeric values (numbers) and variables are in the right place. Then cross-multiply. Solve the equation for your answer (money for minutes). I used the variable m, as I find it helps if it relates to your problem. M is for money. Hope this helps!

Step-by-step answer
P Answered by PhD

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
