Answer: C 4
Step-by-step explanation:
Use the formula: distance = rate x time
We can say that train 1 travels a distance of x, and train 2 travels a distance of 700 - x
The rate of train 1 is 75 mph, and the rate of train 2 is 100 mph
The time traveled for the two trains will be the same. We can represent that with the variable t.
We have the following equation for train 1:
x = 75t
For train 2, we have this equation:
700 - x = 100t
Use the Substitution Method by replacing x in the equation for train 2 with the value 75t.
700 - 75t = 100t
700 = 175t
700/175 = 4 hours.
It will take 4 hours for the two trains to meet.
26+5= 31 correct?
So lets make a chart(ish lol)
Hours $$$
1 3
2 6
3 9
4 12
5 15
6 18
7 21
8 24
9 27
10 30
11 33
To get atleast 31 dollars you need to work 11 hours.
If you want fractions they need to work 10 1/3 hours
Hope this helped!
Area of rectangle is length x width
area of smaller rectangle
9x5=45
area of large rectangle
11x7=77
77-45=32
