Answer:

  1.2 hours

Step-by-step explanation:

A fills 1/2 tank per hour; B fills 1/3 tank per hour, so together they fill ...

  1/2 +1/3 = 3/6 +2/6 = 5/6 . . . . tank per hour

The reciprocal of this rate give the rate in the units we want:

  6/5 hours per tank.

__

At that rate, it will take 6/5 = 1.2 hours to fill the tank.

The percentage when Potiphar woke up late is 14.4%.

<h3>How to calculate the percentage?</h3>

From the information, it was stated that Potiphar takes a horse and buggy to work everyday. In order to come on time, he must wake up promptly at 6.30am and then hop on the buggy and that anytime he wakes up late or the horse was in traffic, he will be late.

It was further illustrated based on the information given in the question that he was late 24.4% of the time and the horse was in traffic for 10% of the time.

Therefore, the percentage when he woke up late will be gotten by simply subtracting the percentages that we have above. This will be illustrated below:

= 24.4% - 10%

= 14.4%

Therefore, the percentage when Potiphar woke up late is 14.4%.
