Question

Suppose you travel to Africa and drop a note in a sealed bottle in the Nile at its source. If the bottle traveled at 7 km/h on average in the river, how long would it take the bottle to reach the muth of the nile? (the nile, the world longest river, is 6741 km long)

Answer 1

The time required for the bottle to reach the end of Nile is 963 hours

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. 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

Speed = Distance / Time

Given data ,

Let the speed of the bottle in the river be S = 7 km/h

Let the distance traveled by the bottle in the river be D = 6741 km

Now , the time taken by the bottle to reach the distance D with speed S is calculated by the equation

Speed = Distance / Time

and ,

Time = Distance / Speed

Substituting the values of distance and speed in the equation , we get

Time taken by the bottle = 6741 / 7

                                          = 963 hours

Therefore , the time required is 963 hours

Hence , The time required for the bottle to reach the end of Nile is 963 hours
