Question

. The width of a beach at 8:00 p.m. is 36 m. At
3:00 a.m., the width of the beach narrows to
8 m due to the high tide. What is the average
rate of change per hour of the beach width?​

Answer 1

Answer:

A= 1.142 m/hr

Step-by-step explanation:

Width of beach at 8 p.m. = 36 m

Width of beach at 3 a.m. = (36-8) m =28 m

Average change in width(A) = change in width (Width of beach at 8 p.m.-Width of beach at 3 a.m.0/ time in hours

A= ( 36-28)/ 7

A= 8/7 m/hr

A = 1.142 m /hr

Thanks

Answer 2

Answer:

A= 1.142 m/hr

Step-by-step explanation:

Width of beach at 8 p.m. = 36 m

Width of beach at 3 a.m. = (36-8) m =28 m

Average change in width(A) = change in width (Width of beach at 8 p.m.-Width of beach at 3 a.m.O/ time in hours

A= ( 36-28)/ 7

A= 8/7 m/hr

A = 1.142 m /hr
