Answer:
4 hours
Step-by-step explanation:
The speed of the first car is
While the speed of the second car is
The time it takes for each car to cover a distance d is
where
d = 960 km is the total distance covered
For car 1, the time taken is:
For car 2, the time taken is:
Therefore, the difference in time is:
Answer:
2y=11 - 5x
Step-by-step explanation:
An equation that is parallel shares the same gradient thus
2y= -5x - 8
y = -5/2x- 4
gradient m = -5/2
substitute value of m and the co-ordinates into a new linear equation
y = mx + c
-9 = (-5/2)(8) + c
c = 20-9 = 11
thus y = -5/2x + 11
2y=11 - 5x
3x+2−x=11x−9
Step 1: Simplify both sides of the equation.
3x+2−x=11x−93x+2+−x=11x+−9(3x+−)(2)=11x−9
(Combine Like Terms)
2x+2=11x−92x+2=11x−9
Step 2: Subtract 11x from both sides.
2x+2−11x=11x−9−11x−9x+2=−9
Step 3: Subtract 2 from both sides.
−9x+2−2=−9−2−9x=−11
Step 4: Divide both sides by -9.
−9x−9=−11−9x=119
ANSWER: 11/9
