Question

A company manufacturing paper coffee cups produces 540 paper coffee cups every half hour . How many lapsed coffee cups will be produced in 3 hours and 30 minutes , 5 hours 15 minutes 8 hours 45 minutes

Answer 1

Answer:

$C_{3.5h}=3780 \ cups\\\\C_{5.25hr}=5670\ cups\\\\C_{8.75hr}=9450\ cups$

Step-by-step explanation:

The rate of production is 540 per 0.5hr=>1080 per hour.

Let t be the number of hours. We convert the times in hours only(1 hr=60mins)

• 3hrs 30 mins=3.5hrs
• 5hrs 15mins=5.25hrs
• 8grs 45 mins=8.75hrs

#We therefore multiply directly to find the number of cups after t hours:

$C_{3.5h}=1080\times 3.5\\\\=3780 \ cups\\\\C_{5.25hr}=1080\times5.25\\\\=5670\ cups\\\\C_{8.75hr}=1080\times 8.75\\\\=9450\ cups$
