You want to find the value of x, and you know that y = 3.
1) First plug y = 3 into the equation:
7x + 2y = 48
7x + 2(3) = 48
7x + 6 = 48

2) Now solve the equation 7x + 6 = 48 for x by subtracting 6 from both sides, then dividing both sides by 7.
7x + 6 = 48
7x = 42
x = 6

--------

Answer: x = 6

I think
A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it
