D. 53.659 seconds
explanation: 27.98+25.679 = 53.659
Answer:
Step-by-step explanation:
- Speed = Distance/Time
- => Speed = 15 km ÷ 13/60
- => Speed = 15 km ÷ 0.216
- => Speed = 15 km/0.216
- => Speed = 15 x 4.63/0.216 x 4.63
- => Speed = 69.45 km/1 h (Approximate)
<u>Conclusion:</u>
- Therefore, the speed is 69.45 km/h (Approximate)

Given :
A line 18x - 3y = -45 .
To Find :
The slope of a line parallel to the given line.
Solution :
Simplifying given equation in form of :
y = mx + c.

So, slope of above equation is 6.
Therefore, the slope of a line parallel to the given line is 6.
Hence, this is the required solution.
I'm pretty sure the answer is C. 168 units ^2
