The distance traveled by Davis family = 35 miles
Time taken to cover the distance = 
hour
Speed = Distance 
Time
Speed = 
Speed = 
So, speed = 70 miles/hour.
At 2:00 pm, the family destination was 245 miles away.
So, the number of hours, when the family was 245 miles away = 
= 3.5 hours
So, after 3.5 hours, that is at 5:30 pm, the Davis family will be 245 miles away.

Answer:
80
Step-by-step explanation:
Rounding to the nearest tenth, we get:
100, 80, 40, 90, 80, 100, 90, 90, 80, 80, 80
Number no. of times
80 occurs 5 times (most of the times) so, 80 will be the mean.

It is given that, Mrs. Jones bought three 2-kilogram packages of flour.
And
And three 2 -kilogram packages means she bought 6 kilogram flour .
So we need to convert 6 kilogram flour into grams.
If,
So she bought 6000 grams of flour .
The slope of the tangent at a given point can be found by differentiating the given equation and substituting the value of x at the point as such:
y = 9 - x²
dy/dx = -2x; x = 1
dy/dx = -2
For a line with the slope of -2 and passing through point (1 , 12)
y -12 = -2(x - 1)
