Mariana tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds, 148.5 milliliters of slushy remained. How long did it take for her to finish the slushy if she originally started with 225 milliliters? Who finished first?

This is what i did to get the answer.

225/ 4.5 = 50 seconds to finish the slushy.
