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

Sarah is making a scale drawing of a painting that is 48 in. wide by 120 in tall. her paper is 12 in. wide and 24 in. tall. she

Volgvan

Answer:

No it is not a reasonable scale. She should use 1 inch= 6 inches.

Step-by-step explanation:

The width of the drawing is 48 inches, dividing it by 4 inches gives 48/4=12 inches.

This is exactly the width of her paper. Which means the drawing will get to the edge.

The height of the drawing is 120 inches,divide by 4inches you get: 120/4=30 inches. The height of paper is 24 inches. Which means her paper is too small to accommodate the height of the drawing. The preferred scale would be 1 inch=6inches.
