A penguin walks 10 feet in 6 seconds. At this speed:

Leya [2.2K]

The penguin will walk 75.15 feet in 45 sec

It will take the penguin 26.95 sec to walk 45 feet

Step-by-step explanation:

Given

Distance = d = 10 feet

Time = t = 6 sec

First of all we have to calculate speed

Let s be the speed, then

$s=\frac{d}{t}\\=\frac{10}{6}\\=1.67\ ft\ per\ sec$

Now,

How far does the penguin walk in 45 seconds?

Here we know the speed and the time

So,

s=1.67 ft per sec

t = 45 sec

So,

$s=\frac{d}{t}\\1.67=\frac{d}{45}\\1.67*45=d\\d=75.15\ feet$

How long does it take the penguin to walk 45 feet?

Here we know

d =45 feet

and

Speed =s =1.67 ft per sec

So,

$s=\frac{d}{t}\\1.67=\frac{45}{t}\\t=\frac{45}{1.67}\\t=26.95\ sec$

The penguin will walk 75.15 feet in 45 sec

It will take the penguin 26.95 sec to walk 45 feet

How do I solve this

Oxana [17]

9514 1404 393

Answer:

h ≈ 448.0 m

Step-by-step explanation:

The relevant trig function is the one that relates adjacent side length, opposite side length, and angle:

Tan = Opposite/Adjacent

Solving for the adjacent side length, we get ...

Adjacent = Opposite/Tan

For the two angles given, we want the value of the difference of the adjacent side lengths:

168 m = h/tan(41.2°) -h/tan(52.5°)

Then h is found by dividing by its coefficient:

h = (168 m)/(1/tan(41.2°) -1/tan(52.5°))

h ≈ 448.0 m
