Answer:

72 houses.

Step-by-step explanation:

We are told that a postal worker can deliver the mail to 18 houses in 15 minutes.

Let us find numbers of mails delivered by postal worker per minute.

\text{Number of mails delivered per minute}=\frac{18\text{ houses}}{15\text{ minutes}}

\text{Number of mails delivered per minute}=1.2\frac{\text{ houses}}{\text{ minute}}

Since we know that 1 hour equals 60 minutes, so we will multiply 1.2 by 60 to find the number mails postal worker will deliver in 1 hour.

\text{Number of mails delivered in 1 hour}=1.2\frac{\text{ houses}}{\text{ minute}}\times 60\frac{\text{minutes}}{\text{hour}}

\text{Number of mails delivered in 1 hour}=1.2\times 60\frac{\text{ houses}}{\text{hour} }

\text{Number of mails delivered in 1 hour}=72\frac{\text{ houses}}{\text{hour} }

Therefore, the postal worker will be able to deliver mails to 72 houses in 1 hour.

A teacher is four time as old as a student .in 20 years, the student 's age will be half of the teacher 's age. How old are they
notka56 [123]
Let the present age of student be x
Present of teacher will be 4x

After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20

According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10

So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.
