Answer 1

Problem 1.
1 day = 24 hours
58 days = 24 * 58 = 1392 hours
60 minutes = 1 hour
30 minutes = 30/60 hour = 1/2 hour
It takes Keurig a total amount of time of 1392 + 15 + 1/2 = 1407 * 1/2

Problem 2.
Part A: 1 foot = 12 inches 0.5 feet * 12 inches = 6 inches per day
Part B: 1 day = 24 hours 6 inches/24 hours = 0.25 inches per hour

Answer 2

It takes Keurig a total amount of time of 1392 + 15 + 1/2 = 1407 * 1/2
