Answer:
8.5 miles
Step-by-step explanation:
The question is asking for the total distance covered by Clarke in miles. To figure this out, you must add together all the miles he ran.
2.8 + 2 + 3.7
This gives you an answer of 8.5.
=21x + 35y + 4y
= 21x + 39y
Rate of change= (y2-y1)/(x2-x1)=(306-360)/(16-10)= - 54/6= - 9
