tino4ka555 [31]

Answer:

684 Hours.

Step-by-step explanation:

If the plane travelled that distance in 5 hours, then all you need to do is divide the distance by 5 to get the distance travelled in one hour. This is obviously presuming that the speed travelled was constant or that this is an average figure.

3420/5 = 684.

Mary has 6 pairs of blue pants which represents 40% of slacks in her closet. What is the total number of pants she owns

Anastaziya [24]

Answer:

The total number of pants in Mary's closet = 15

Step-by-step explanation:

Here, given:

40% of slacks in her closet = 6 pairs

Let us assume the total pants in her closet = m

So, according to the given data:

40% of m = 6 pairs

$\implies \frac{40}{100} \times m = 6\\\implies m = 6 \times \frac{100}{4} = 15$

⇒ m = 15

Hence the total number fo pants in her closet = 15
