*disclaimer*
dont know if this is how you were taught to do this but heres how i was:
![6 sec /10 ft. = 45 sec / x](https://img.qammunity.org/2021/formulas/mathematics/college/ujs7y2304qh82fo9vseqyqxbzc3h1iax72.png)
Set this up as a proportion.
Then multiply 10 ft by 45 sec, and 6 sec by x
Your equation then simplifies to
6x = 450
x = 75
