This trip would take 2 hours and 15 minutes, since 1,991.25/885=2.25. This means it would take two hours and 25/100 (1/4) of an hour. 1/4 of an hour is 15, so you add 15 minutes to 2 hours.

Answer:

It took 2 hours and 15 minutes for the airplane to travel 1,991.25 Km

Step-by-step explanation:

In order to find the time, you need to use the fact that average speed = distance traveled/time taken, the problem gives you that the distance traveled is equal to 1,991.25 Km and the average speed is 885 Km/h.

So, you use these values to find the time taken as follows:

time = \frac{distance}{speed}=\frac{1991.25 km}{885 \frac{km}{h}} = 2.25 h

2.25 is a number made by two parts: integer-part and fractional-part.

The integer-part is equal to 2 hours.

The 0.25 is the fractional-part and corresponds to the minutes. 0.25 in fraction is 0.25 = \frac{1}{4}, the hour has 60 minutes, so when you divided by  \frac{1}{4} you the get 15 minutes.

Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $1
Olenka [21]

Answer:

\$16,826,000.

Step-by-step explanation:

We have been given that Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $15,342,000 the third quarter, and a loss of $48,037,000 for the fourth quarter.

To find the net profit for year, we will subtract the loss in the 4th quarter from the sum of profit in 3 quarters as:

\text{Net profit for the year}=\$28,951,000+\$20,570,000+\$15,342,000-\$48,037,000

\text{Net profit for the year}=\$64,863,000-\$48,037,000

\text{Net profit for the year}=\$16,826,000

Therefore, the net profit for the year was \$16,826,000.
