If you can walk 3 1/3 miles in an hour, how many miles can you walk in 30 minutes, given the

Vedmedyk [2.9K]

Answer:

d = 1.67 miles

Step-by-step explanation:

Given that,

Speed of a person, $s=3\dfrac{1}{3}\ mph$

We need to find how many miles can you walk in 30 minutes, given the same pace.

30 minutes = 0.5 h

$3\dfrac{1}{3}\ mph = \dfrac{10}{3}\ mph$

Speed = distance/time

$d=v\times t\\\\d=\dfrac{10}{3}\ mph\times 0.5\ h\\\\d=1.67\ miles$

So, the person will cover a distance of 1.67 miles

Two people are 100 feet apart on opposite sides of a tree. The angles of elevation from the people to the top of the tree are 30

cricket20 [7]

We need to solve for the height of the tree given two angles and distance between the two observers. See attached drawing for a better understanding of the problem.
We derive to equations using SOH CAH TOA such as below:
sin30 = h / x
sin 45 = h / (100-x)

sin 45 (100-x) = xsin30
70.71 - 0.71x = 0.5x
70.71 = 1.21 x
x = 58.44

Solving for h, we have:
h = xsin30
h = 58.44 sin30
h = 29.22

The height of the tree is 29.22 feet.
