A motorboat can maintain a constant speed of 15 miles per hour relative to the water. The boat makes trip upstream to a certain
Ira Lisetskai [31]

Answer:

The speed of the current is 2 miles per hours

Step-by-step explanation:

Given as :

The speed of motorboat = x = 15 miles per hour

The time taken by motorboat trip upstream = 51 minutes

The time taken by motorboat trip downstream = 39 minutes

Let The speed of the current = y miles per hour

Let The total distance cover = A miles

So ,

Speed = \dfrac{\textrm Distance}{\textrm Time}

So, x - y = \dfrac{A}{51}

I.e  15 - y =  \dfrac{A}{51}

And x + y = \dfrac{A}{39}

I.e  15 + y = \dfrac{A}{39}

\dfrac{x-y}{x+y} = \dfrac{39}{51}

I.e \dfrac{x-y}{x+y} = \dfrac{13}{17}

Or, 17 × (x - y) = 13 × (x + y)

Or, 17 x - 17 y = 13 x + 13 y

Or, 17 x - 13 x = 13 y + 17 y

Or, 4 x = 30 y

Now, ∵ x = 15 miles per hour

So, 4 × 15 = 30 y

Or, y =  \dfrac{60}{30}

∴   y = 2 miles per hour

Hence The speed of the current is 2 miles per hours   Answer

We wish to know how much faster Grant rows than Arianna.

d=G-A  and we want our answer is miles/hour so

d=(6mi/36min)(60min/hr)-(3520yd/20min)(mi/1760yd)(60min/hr)

d=10mph-6mph

d=4mph

So Grant rows 4 miles per hour faster than Arianna.
