A bird leaves its nest and travels 18 miles per hour downwind for 2 hours. On the return trip, the bird travels 3 miles per hour
Darya [45]

Answer:

Step-by-step explanation:

Let y represent the distance travelled downwind by the bird from its nest.

Distance = speed × time

A bird leaves its nest and travels 18 miles per hour downwind for 2 hours. Distance covered in travelling downwind is

2 × 18 = 36 miles

On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after 3 hours. It means that the speed at which the bird travelled is 18 - 3 = 15 mph. Also, the distance covered in 3 hours is 36 - 5 = 31 miles. Therefore,

a) distance of the entire trip is

36 + 36 = 72 miles

b) time spent in travelling downwind from its nest is 2 hours

Time for the return part is

3 hours + 5/15 = 3 + 1/3 × 60 minutes

= 3 hours 20 minutes

Total time for the trip is

2 hours + 3 hours 20 minutes

= 5 hours 20 minutes 0 seconds

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary.
Rama09 [41]

Check the picture below.

now, we have a triangle with all three sides, thus we can use Heron's Area Formula on the triangle.

\bf \qquad \textit{Heron's area formula} \\\\ A=\sqrt{s(s-a)(s-b)(s-c)}\qquad \begin{cases} s=\frac{a+b+c}{2}\\[-0.5em] \hrulefill\\ a=10\\ b=26.695\\ c=22\\ s=29.3475 \end{cases} \\\\\\ A=\sqrt{29.3475(29.3475-10)(29.3475-26.695)(29.3475-22)} \\\\\\ A=\sqrt{29.3475(19.3475)(2.6525)(7.3475)}\implies A\approx \sqrt{11066.007} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill A\approx 105.195~\hfill
