The addition is one of the four fundamental mathematical operations. Jenny can have dinner at 7 pm and 7.5 mins.
<h3>What is Addition?</h3>
The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
The time can be calculated as,
- Time taken for preparation = 30 min
- Time is taken to travel to airport = 25 mins
- She will wait for 10 mins before the flight arrive = 10 min
Flight lands at 4 pm
- She will leave 15 mins after the flight lands = 15 mins
- It takes 25 mins to travel back home ⇒ 15 + 25 mins
- She will start cooking after 5 mins ⇒ 15+25+5 min
Jenny has bought a 2.4kg chicken. It takes 35-45 minutes per kg plus an additional 30 minutes to cook the chicken. Time needed for cooking the chicken = (2.5×45 + 30) = 142.5 min
⇒ 15+25+5+142.5 min
Thus, the total time it takes for Jenny to cook the food starting when the flight lands are ⇒ 187.5 mins = 3 hours 7.5 mins
Since the flight lands at 4 pm
⇒ 4 pm + 3 hours 7.5 mins
⇒ 7 pm and 7.5 mins
Hence, Jenny can have dinner at 7 pm and 7.5 mins.
