A race car travels at a speed of 230 miles per hour. The race track on which the car is competing is 400 miles long. About how long does it take for the car to finish, disregarding pit stops and yellow flags?
A) 174 minutes
B) 345 minutes
C) 1 hour 45 minutes
D) 2 hours 14 minutes
Answers
S = Speed
D = Distance
T = Time
First we need to re-arrange this formula to solve for time
T= D/S
T = 400/230
T=1.74 hours
.74 hours is close enough to .75 that we can say it is 45 minutes
So it is 1 hour and 45 minutes
Answer:
Option(c)
Step-by-step explanation:
The race track on which the car is competing miles= 400 miles
A car travels with speed= 230 miles per hour
We have to find time taken for the car to finish
As we know,
Time taken to cover certain distance=[tex]\frac{Distance}{Time}[/tex]
Time taken to cover certain distance=[tex]\frac{400}{230}[/tex]
Time taken to cover certain distance=[tex]\frac{40}{23}[/tex]
Time taken to cover certain distance=1 hour 45 minutes
Hence, the correct answer is option(c)

The number of days Jared will take to make 20 bird houses, when he can make 4 bird houses in 3 days, is 15 days.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
[tex]W=\dfrac{1}{n}[/tex]
Jared made 4 bird houses in 3 days. Thus, the number of bird houses made by Jared in 1 day is,
[tex]n=\dfrac{4}{3}[/tex]
Thus, the Jared made 4/3 housed in a single day. By this rate the total time required to Jared to make 20 bird housed is,
[tex]t=\dfrac{20}{\dfrac{4}{3}}\\t=\dfrac{60}{4}\\t=15\rm\;days[/tex]
Hence, the number of days Jared will take to make 20 bird houses, when he can make 4 bird houses in 3 days, is 15 days.

a wireless company offers two cell phone plans. Plan A charges 24.95 per month plus 0.10 per minute for calls. Plan B charges 19.95 per month plus 0.20 per minute. Use the questions to find when the two plans cost the same.
Answers
To find when the two plans cost the same, set up an equation equating the cost of Plan A and Plan B. Solve for the number of minutes used when the two plans cost the same.
Explanation:To find when the two plans cost the same, we need to set up an equation where the cost of Plan A is equal to the cost of Plan B. Let x be the number of minutes used. For Plan A, the cost is $24.95 + $0.10x. For Plan B, the cost is $19.95 + $0.20x. Setting these two expressions equal to each other, we get:
$24.95 + $0.10x = $19.95 + $0.20x
Now, we can solve for x:
$0.10x - $0.20x = $19.95 - $24.95
$-0.10x = -$5
x = -$5 / -$0.10
x = 50
Therefore, the two plans cost the same when 50 minutes are used.

It will Marvin 12 days to exercise 576 minutes if he exercises 48 minutes every day

Total minutes desired: 576 minutes
Daily exercise duration: 48 minutes
To determine the number of days required, we perform the following calculation:
Divide 576 by 48.The result is the number of days Marvin needs to exercise to reach 576 minutes.576 minutes ÷ 48 minutes/day = 12 days
Therefore, it will take Marvin 12 days of exercising for 48 minutes each day to accumulate 576 minutes of exercise.
