It forms a Triangle, in which base is shadow, and height of the tree is perpendicular.

So, Tan Ф = P / B
Tan 28 = P /18
0.53 * 18 = P [ Tan 28 = 0.53 ]
P = 9.6

In short, Your Answer would be Option D

Hope this helps!

A typical marathon is 26.2 miles. Allan averages 12 kilometers per 1 hour when running in marathons. How long does it take for A

cluponka [151]

Answer:

3.5 hours

Step-by-step explanation:

Given: Distance= 26.2 miles

Speed= 12 km/h

First lets convert the unit of speed from kmh to mph.

Remember, 1 mile= 1.609 km

∴ For speed of 12 km/h= $\frac{12}{1.609}= 7.45\ mph$

Speed= 7.45 mph

Next, find time taken by Allan to complete a Marathon.

$Time= \frac{Distance}{speed}$

⇒ Time= $\frac{26.2}{7.45}$

∴ Time= 3.516 hours ≅ 3.5 h (nearest tenth)

∴ Allan took 3.5 hours to complete marathon.
