Answer: It took Sean 55 seconds to drink all the slushy
Solution:
Original Volume: Vo=275 milliliters
After t1=13 seconds, 210 milliliters remained: V1=210 milliliters
He drank the slushy at a constant rate: r
Sean drank V=Vo-V1=275 milliliters-210 milliliters→V=65 milliliters
r=V/t1
r=65 milliliters / 13 seconds
r=5 milliliters/second
Sean will drink the remained volumen in a time t2:
t2=V1/r
t2=210 milliliters / (5 milliliters/second)
t2=42 seconds
Total time to drink: t
t=t1+t2
t=13 seconds + 42 seconds
t=55 seconds
