Answer:
40 miles, 2000seconds or 33minutes and 20 seconds
Step-by-step explanation:
a. multiple time by miles/hour -> 40*60/60=40 so 40 miles
b. 60+12=72 so her new speed is 72mph. next, to find the time we need to divide distance by 1/mph -> 40* 1/(72/60)=40*60/72=100/3 which is 2000seconds or33minutes and 20 seconds

a teacher brought to class a pack of notebooks. if her gives his students 5 notebooks to each, he will have 7 notebooks left. if he tries to give each student 7 notebooks, he will be 5 notebooks short. how many students are there in the class?
Answer:
6 students
Step-by-step explanation:
Let the number of notebooks be $x$ and the number of students be $y.$
If there are 5 notebooks per student, we have:
$x-5y=7$
Simliairly, we have 7 notebooks per person, which is:
$x-7y=-5$
Then, using system of equations, we can add multiply the first equation by $-1$ and then add.
We would have:
$-1(x-7y=-5)=-x+7y=5$
Then, adding gives us:
$2y=12$
$y=6$
There are 6 students in the class.
Let x represent the number of students that are there in the class.
The teacher her gives his students 5 notebooks each, and still has 7 notebooks left.
The number of note books = 5x + 7 (1)
The teacher her gives his students 7 notebooks each, and was 5 notebooks short.
The number of note books = 7x - 5 (2)
Therefore equating equations 1 and 2:
5x + 7 = 7x - 5
7x - 5x = 7 + 5
2x = 12
x = 6
There are 6 students in the class.
