If it takes 4 men 6hours to repair a road, how long will it take 7 men to do the job if they work at the same rate.
Crank
Tricky question. This isn't a ratio question even though it seems like one.

First divide 7 by 4.
7 \div 4 = 1.75

With more men, the hours taken to repair a road will be even shorter.

So next divide 6 by 1.75.
6 \div 1.75 = 3.43

Answer : It'll take 3.43 hours to do the job if they work at the same rate.

Hope this helps. - M

Find the coordinates of the midpoint of the segment with the given endpoint S(-1,5) and T(7, -2)
qaws [65]

Answer:

The answer is

<h2>(3  \: , \:  \frac{3}{2} )</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} ) \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

S(-1,5) and T(7, -2)

The midpoint is

M = ( \frac{ - 1 + 7}{2}  \:  ,  \:  \frac{ - 2 + 5}{2} ) \\  = ( \frac{6}{2}  \: , \:  \frac{3}{2} )

We have the final answer as

(3  \: , \:  \frac{3}{2} ) \\

Hope this helps you
