Question

During low tide, the beachfront in some places is about 350 from the ocean to the homes . High tide can change the width of a beach at a rate of -17 feet each hour . It takes 6 hours for the ocean to move from low to high tide . What is the change in the width of the beachfront from low to high tide ?

Answer 1

the change in width would be -17 * 6 = -102 feet

distance from the ocean to the houses would be 350-102= 248 feet
