Let after t hours the distances D1 traveled by car A
D1 = 30 t
Car B starts at 10 am and will therefore have spent one hour less than car A when it passes it.
After (t - 1) hours, distance D2 traveled by car B
D2 = 40 (t - 1)
When car B passes car A, they are at the same distance from the starting point and therefore<span> D1 = D2 </span>
30 t = 40 (t - 1)
Solve the equation for t,
30 t = 40t - 40
10 t = 40
t = 4
<span> Car B passes car A at = 9 + 4 = 1 pm.</span>
Area = (8 x 10) + 1/2(5)(4)
Area = 80 + 10
Area = 90
Answer
B) 90 cm^2
Answer:
I: Slope = 1
x= 5/1 or 5.00000
y= 5/-1 0r 5.00000
2: Slope = -8.000/2.000 or 4.000
x= 5/2 or 2.50000
y= 10/1 or 10.00000
