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

Verified Answer :

No, Colin is not correct. He needs to subtract first to get the total distance and then divide by the rate. He should have put parentheses around 104–28 and then divided by 4 to get the answer of 19 minutes.

No, Colin is not correct. Katy requires 19 minutes to reach the sea floor.

What is Speed?

Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

Total distance between sea level and sea floor is 104 feet.

Katy is available 28 feet below sea level.

so, remaining distance katy needs to  move = 104 - 28 feet

                                                                         = 76 feet

Speed of Katy for moving downwards = 4 feet per minute

Time taken by Katy to reach sea floor = \(\frac{distance}{speed}\)

                                                               = 76/4

                                                               = 19 minutes

Thus, Katy requires 19 minutes to reach the sea floor.
