"20",
"72",
"56",
"30"
] | C | Total distance = 72
Distance = Speed * Time
Walking speed = s1 = 8
Walking time = t1
Bike speed = s2 = 16
Time traveled in bike = t2
d1 + d2 = 72
s1t1 + s2t2 = 72
8*t1 + 16*t2 = 72
t1 + 2*t2 = 9 ----- (1)
Given: t1 + t2 = 8 ----- (2)
(1) - (2) --> t2 = 1 and t1 = 8 - 1 = 7

In the coordinate plane, Line A has a slope of -1 and an x-intercept of 1. Line B has a slope of 3 and a y-intercept of -3. If the two lines intersect at the point (a,b), what is the sum a+b? | [
"2",
"0",
"1",
"4"
] | C | The equation of Line A is y = -x + 1
The equation of Line B is y = 3x - 3
3x - 3 = -x + 1
x = 1
y = 0
The point of intersection is (1,0) and then a+b = 1.
The answer is B. | AquaRat_train |
