7. It takes a middle school student's body 5 hours to metabolize 7 of the caffeine in a Shamrock Shake. There are

320 mg of caffeine per shake. Erin wakes up on St. Patty's Day and drinks 3 Shamrock Shakes at 7 a. M. By what

time will Erin's body have metabolized the caffeine to 60 mg?

Answer :

The time that Erin's body would metabolize 60 mg of caffeine is 8: 52 : 50 am.

What time would Erin's body have metabolised 60 mg of caffeine?

The first step is to determine the time it would take to metabolize 1 mg of caffeine: 5 / (1/2 x 320) = 5/160

The second step is to multiply 5/160 by 60.

5/160 x 60 = 300 / 160 = 1 140/160 = 1 7/8 = 1 hour 52 minutes 50 seconds. = 8: 52 minutes : 50 seconds
