We can use the factor label method for this problem. The real hint to these types of equations are the units. In this case the units are in miles per hour for the rate.
15 miles/ 2.5 hours = 6mph or 6 miles/hours
If his rate was 1 mph slower we just subtract 1 from 6 mph
6mph - 1mph= 5 mph.

Hope this helps, good luck.

Answer:

5 miles per hour.

Step-by-step explanation:

To solve this problem we first have to calulate the rate at which Justin ran the first day, that is done by dividing the distance by the time:

Rate=distance/time

Rate= 15/2.5

Rate= 6 miles per hour

Since he ran at 6 miles per hour and the next day he ran 1 mile per hour slower he would have run at a 5 mph rate the next day.

In a plot of probability of finding the electron in the hydrogen ground state versus the distance from the nucleus, the maximum
Lunna [17]

In a plot of the probability of finding the electron in the hydrogen ground state versus the distance from the nucleus, the maximum occurs (A) at a0. the first Bohr radius.

<h3>What is an electron?</h3>
  • The electron is a subatomic particle with a negative one elementary charge electric charge.
  • Electrons are the first generation of the lepton particle family and are widely regarded as elementary particles due to the lack of known components or substructure.

Electron in the hydrogen:

  • Hydrogen has the simplest electron configuration to write because it just contains one electron.
  • There is essentially only one electron surrounding the Hydrogen nucleus.
  • Because hydrogen only has one electron, its configuration is 1s1.
  • The maximum occurs at a0, the first Bohr radius, in a plot showing the chance of finding the electron in the hydrogen ground state vs the distance from the nucleus.

Therefore, in a plot of the probability of finding the electron in the hydrogen ground state versus the distance from the nucleus, the maximum occurs (A) at a0. the first Bohr radius.

So first you’d add the numbers together 31+36+18=85 boys
Then
34+44+26=104 girls
Then add 85+104=189 in total
Then divide 189/104=.055 so C
