If the question is 7 x 200+50+6 it equals 1792
Answer:
The middle between two numbers is the average of those numbers. So we add those two numbers together and divide by two. And the answer is (1 + 6) / 2 = 3.5
The total cost would be $4,050. Hope this helps!
I assume a unit rate is simply ms^-1 or whatever.
In order to determine m/s one must make the "per whatever" part equal to 1. In this case it is seconds, so we must make seconds equal to 1.
If in 17 seconds it travels 238 metres, that means in 1 second it travels 238/17m=14m
Therefore the unit rate (speed) of the car is 14m/s or 14ms^-1
