Pratap puri rowed 10 miles down a river in 2 hours, but the return trip took him 2 and one half hours. Find the rate pratap can

N76 [4]

Answer:

Rate of Pratap in still water is 4.5 miles/hour and rate of current is 0.5 miles/hour.

Step-by-step explanation:

Pratap Puri rowed 10 miles down a river in 2 hours, but the return trip took him 2.5 hours.

We know that, $Speed = \frac{Distance}{Time}$

So, the speed of Pratap with the current will be: $(\frac{10}{2})miles/hour = 5$ miles/hour

and the speed of Pratap against the current will be: $(\frac{10}{2.5})miles/hour = 4$ miles/hour.

Suppose, the rate of Pratap in still water is $x$ and the rate of current is $y$ .

So, the equations will be........

$x+y= 5 .............................. (1)\\ \\ x-y=4 .............................. (2)$

Adding equation (1) and (2) , we will get......

$2x=9\\ \\ x=\frac{9}{2}= 4.5$

Now, plugging this $x=4.5$ into equation (1), we will get.....

$4.5+y=5\\ \\ y=5-4.5 =0.5$

Thus, Pratap can row at 4.5 miles per hour in still water and the rate of the current is 0.5 miles/hour.

Count back 25 minutes from 4:15 and you’ll get 3:50. The numbers on the clock are 5 minutes apart. It should be easy to solve just by using a standard clock

Find the midpoint of the line segment whose endpoints are the given points. (-24.6, 38.1) and (-25.7, -17.7)

CaHeK987 [17]

Answer:

Midpoint is $(-25.15,10.2)$

Step-by-step explanation:

A line segment refers to line that has two endpoints.

Let $(a,b),(c,d)$ be the endpoints of a line segment.

Midpoint of the line segment is given by $(\frac{a+c}{2} ,\frac{b+d}{2})$

Take the given points as follows:

$(a,b)=(-24.6,38.1)\\(c,d)=(-25.7,-17.7)$

Midpoint of a line segment $=(\frac{-24.6-25.7}{2},\frac{28.1-17.7}{2})$

$=(\frac{-50.3}{2} ,\frac{20.4}{2} )\\=(-25.15,10.2)$
