Cas walks 3/5 miles in 24 min at a steady pace, how long does it take him to walk 2 miles?

san4es73 [151]

Your answer is 80 mins, or an hour and 20 mins. You simply turn that fraction to a decimal by diving 3 with 5. This should turn out to be 0.6. Then you multiply the 24 mins with the 2 miles and it turns out to be 48. After this, you divide 48 by 0.6 and you get 80.

masha68 [24]

The initial length of the blue ribbon = 1.6 meters

Step-by-step explanation:

Here, according to the question:

The initial length of orange ribbon = 2 meters

Let us assume the initial length of blue ribbon = S meters

Now, the length of blue ribbon = (4/5) times the length of orange ribbon

$\implies S =( \frac{4}{5})$ x Length of Orange ribbon

$\implies S = (\frac{4}{5}) \times 2 = 1.6$

or S = 1.6 meters

Hence, the initial length of the blue ribbon is 1.6 meters.

<h3>What is liner equation?</h3>

A linear equation in mathematics is an equation that can be written as display style a 1x 1+ldots +a nx n+b=0, where x 1, dots, x n are the variables, and display style b, a 1, ldots, a n are the coefficients, which are frequently real integers.

<h3>According to the given information:</h3>

Madison, we first have to add 30 + 31 = 61.

How many times does 61 go into 307

Five,

because 61 x 5 = 305.

This means there are 5 of each classroom.

We still have two students left over, though, so they will have to be added to two of the 30 rooms,

so there are now 7 classrooms of 31 and 3 of 30.
