Question

Sean tried to drink a slushy as fast as he could. He drank the slushy at a constant rate. There were originally \[275\] milliliters of slushy in the cup. After \[13\] seconds, \[210\] milliliters of slushy remained.

How fast did Sean drink?

milliliters per second

How long did it take Sean to drink all the slushy?

 seconds

Answer 1

Shawn drinks at a rate of 5 milliliters/second.

This is done by

275 ml - 210 ml = 65 ml (This is how much he drinks over the 13 seconds in the problem)

65 ml/13 s = 5 ml/s (This is his rate for drinking the slushy)

Now to get how long it takes to drink the whole slushy.

275 ml/5 ml/s = 55 seconds.
