Answer:
37.5 miles per hour
Step-by-step explanation:
The traffic along a stretch road moves at an average speed that carried inversely as the number of cars
Average speed= k/number of cars.
When there are 1,500 cars the average speed is 45
The first step is to calculate the constant k
45= k/1500
k = 1,500 × 45
k= 67,500
Therefore the average speed when there are 1,800 cars can be calculated as follows
Average speed= 67,500/1,800
= 37.5 miles per hour
Hence the average speed is 37.5 moles per hour
Here's a really cool website that let's you input 3D points!

From the attached picture you can see that the point has moved back 5 units, to the left 5 units, and up 5 units.
No she would not be tipping 7 waiters. This is because for every waiter she tips $13.00 shown by 65/5=13. If she wanted to tip 7 waiters at the same rate she would need $91.00 shown by 7*13=91.00.
