In one year, the Perseid meteor shower had a meteor appear every 1 1/5 minutes on average. That same year, the Leonid meteor shower had a meteor appear every 4 2/3 minutes on average. How many more meteors fell during the Perseid meteor shower?

Answer:

325,452 meteors

Step-by-step explanation:

We all know that :

We have 365 days in a year and in each day there are 24 hours, Likewise an hour has 60 minutes

SO, the total number of minutes in a year is :

365 × 24 × 60 = 525600 minutes

For Perseid  meteor:

1 + \frac{1}{5}  \\ \\ = 1 + 0.2 \\  \\ = 1.2

So one meteor fall at 1.2 minutes interval Thus, in a year, we will have :

1 meteor - 1.2 minutes.

x meteor - 525600 minutes.

1.2x = 525600

x = \frac{525600}{1.2}

x = 438000

∴  438,000 meteors fell during the Perseid shower.

For  Leonid meteor shower:

4 + \frac{2}{3} = 4.67

So one meteor fall at 4.67 minutes interval Thus, in a year, we will have :

1 meteor - 4.67 minutes.

x meteors - 525600 minutes.

4.67x = 525600

x = \frac{525600}{4.67}

x = 112548

112,548 meteors fell during the Leonid Shower.

Finally , the numbers of more meteors that  fell during the Perseid meteor shower is calculated by the difference in the number of Perseid meteor shower and Lenoid meteor shower. i.e

438,000 - 112,548 = 325,452

325,452 more meteors fell during the Perseid meteor shower

On the first day of vacation, you read one-quarter of a novel. On the second day, you read half of the remaining pages. On the t
OverLord2011 [107]

The computation shows that the number of pages is 320.

The number of pages read in this second day will be 120.

<h3>How to illustrate the information?</h3>

Fraction read on first day = 1/4

Fraction news on second day = 1/2 × 3/4 = 3/8

Fraction read on last day = 1 - (1/4 + 3/8) =3/8

The number of pages that the book has will be:

= 3/8 × x = 120

0.375x = 120

x = 120/0.375

x = 320

The number of pages is 320.

b. The number of pages read on this second day will be:

= 3/8 × 320

= 120
