[tex] \frac{2.394in}{1min} * \frac{7.489min}{1} = 17.928666in[/tex]
Or 17.93in with significant digits.
To break it down, you can set up your information as a fraction (which I did for the first fraction.) Then you want your units to cancel out, so I put the 7.489 minutes on the top of the next fraction and multiplied them. The min canceled out and left me with in, so I know I had the correct answer.
