Answer:
802,000
Step-by-step explanation:
The number in the thousands place is 1, and the number to the right of it is 5. And if the number to the right is greater than or equal to 5 the place value that you are rounding goes up by one.
Equation of a line is given by y - y1 = m(x - x1); where m is the slope.
y - 4 = 2/5 (x - (-2))
y - 4 = 2/5 (x + 2)
It's simple just divide the total Miles traveled by the total hours;
287 m ÷ 3.5 (it's 3.5 because 30 mins is half of an hour)

= 82 miles per hour
So your final answer would be
82 miles per hour :)
