B. 720
C. 30
D. 132
Answer: (720) is the right answer
Step-by-step explanation:
The distance between hometown and school is 188.75 miles.
Given that, the person drive 110 miles at 55 miles/hour.
Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula , where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.
Due to snow, speed is slow down to 35 miles/hour.
Let x miles be travelled with 35 miles/hour.
Total time taken to travel is 4 hours and 15 minutes.
Here, and
Now,
miles
Total distance = 110+78.75
= 188.75 miles
Therefore, the distance between hometown and school is 188.75 miles.

The total distance from school to the student's hometown is calculated as the sum of distances covered at different speeds. The student spends 2 hours at 55 mi/h, covering 110 miles, and then 2.25 hours at 35 mi/h, covering 78.75 miles, making up a total of 188.75 miles.
The question pertains to the concepts of distance, speed and time in mathematics. In this scenario, the student drives at a speed of 55 mi/h for 110 miles and then slows down due to snowfall and drives at 35 mi/h. From this information, we can calculate the time spent at each speed.
Firstly, since Speed = Distance / Time, we can rearrange to find Time = Distance / Speed. For the first stretch of the journey, the time is 110 miles / 55 mi/h = 2 hours.
It is given that the total journey takes 4 hours and 15 minutes which is equivalent to 4.25 hours. So, the time spent driving at 35 mi/h is 4.25 hours (total trip time) - 2 hours (first stretch) = 2.25 hours.
The distance covered when it was snowing can be found by multiplying this time by the slower speed: 35 mi/h * 2.25 h = 78.75 miles.
Therefore, the total distance from school to the student's hometown is the sum of the distance traveled at each speed: 110 miles (at 55 mi/h) + 78.75 miles (at 35 mi/h) = 188.75 miles.

4x + 5 = 25
The value of x of equation 4x + 5 = 25 is 5.
A linear equation is defined as an equation in which the highest power of the variable is always one.
Given,
4x + 5 = 25
First subtract 5 from both sides,
4x + 5-5 = 25-5
4x=20
Now divide both sides by 4,
x=5
Hence, the value of x of equation 4x + 5 = 25 is 5.

Answer:
Part a)
Part b)
Step-by-step explanation:
we have
60 rev/min
Part a) Find the angular speed in radians per minute
we know that
One revolution represent 2π radians (complete circle)
so
To convert rev to rad, multiply by 2π
Part b) Find the linear speed in inches per minute
we know that
The circumference of a circle is equal to
we have
----> given problem
substitute
Remember that
One revolution subtends a length equal to the circumference of the circle
so
To convert rev to in, multiply by 16π
