Question

What percentage of the seven hours was Farbod awake during the night if there were 21 minutes of awake time during the night?

a) 5%
b) 10%
c) 15%
d) 20%

Answer 1

Farbod was awake for 21 minutes of the night, which is 5% of a total seven-hour night (420 minutes). The calculation is done by dividing 21 by 420 and multiplying by 100 to get the percentage.

Step-by-step explanation:

To find out what percentage of the seven hours Farbod was awake during the night given there were 21 minutes of awake time, we first need to convert hours into minutes for consistency. Since there are 60 minutes in an hour, seven hours equals 420 minutes. Now, we can calculate the percentage by dividing the 21 minutes of awake time by the total 420 minutes and then multiplying by 100 to get the percentage.

Calculation:
(21 minutes awake/420 minutes total) × 100 = 5%

So, Farbod was awake for 5% of the night, which corresponds to option a).
