A car is 500 miles from its destination after 2 hours and 410 miles from its destination after 3.5 hours. What is the rate of change? A. 1.5 miles per hour B. 60 miles per hour O C. 90 miles per hour D. 135 miles per hour

B. 60 miles per hour

Step-by-step explanation:

since the rate you want is mi/hr, divide the change in distance by the change in time.

(500-410)mi / (3.5-2.0)hr = 90mi/1.5hr = 60 mi/hr

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

the correct answer is 5 6 and 7
