Question

The Titanic had a top speed of 28 mph. at that speed, approximately how long would it take all 882ft 9 in of the titanic to pass by?

Answer 1

Hint :To answer this question, we first need to understand what is mph. The number of miles travelled in one hour is expressed in miles per hour, which is a British imperial and US customary measurement of speed. It is used in the United Kingdom, the United States, and a few smaller countries, the majority of which are UK or US territory or have historical ties to the UK or US.

Complete Step By Step Answer:
Speed - The magnitude of the rate of change of an object's position with time or the magnitude of change of its position per unit of time is the speed (often referred to as v) of an item in everyday use and in kinematics; it is thus a scalar number. The average speed of an object in a given time interval is the item's distance travelled divided by the period's duration; the instantaneous speed is the average speed's limit as the interval's duration approaches zero.
As per calculation $ 1ft = 0.000189394{\kern 1pt} {\kern 1pt} {\kern 1pt} Mile $ .
So, converting 882 ft 9 inch into Miles.
 $ 882ft{\kern 1pt} {\kern 1pt} {\kern 1pt} 9{\kern 1pt} {\kern 1pt} in = {\kern 1pt} {\kern 1pt} 0.1671875{\kern 1pt} {\kern 1pt} Mile $ .
 $ speed = \dfrac{{dis\tan ce}}{{time}} $
Putting the given values of speed and distance -
 $ 28 = \dfrac{{0.1671875}}{t} $
 $ t = \dfrac{{0.1671875}}{{28}} $
 $ t = 0.00597{\kern 1pt} {\kern 1pt} Hr $ .
 $ t = 21.495{\kern 1pt} {\kern 1pt} s $ .

Note :
The rate of change of an object's position with regard to a frame of reference is its velocity, which is a function of time. A statement of an object's speed and direction of motion is referred to as velocity. When the object is at rest, its displacement is 0 (the start and ending positions are the same). However, the distance is not zero. The Velocity will be 0 at all times.
