The sea floor is 104 feet below sea level. Katy is 28 feet below sea level. She is moving downward at a rate of 4 feet per minute. Colin used the following calculation to determine how long it will take Katy to reach the sea floor. Is he correct? Explain. 104 – 28 ÷ 4 = 97 minutes
Accepted Solution
A:
The time it will take Katy to reach the sea floor is 19 minutes. How to find time it will take her to reach a depth?The time it will take her to reach the sea floor can be calculated as follows:depth of sea floor = 104 feetKaty height below sea level = 28 feetTherefore, she is moving a downward rate of 4 feet per minute. The time it will take her to reach the sea floor is as follows;depth to cover = 104 - 28 = 76Therefore,rate = distance / time4 = 76 / tcross multiply4t = 76t = 76 / 4t = 19 minutes Therefore, It will take her 19 minutes to reach the sea floor.learn more time here:
