Bobbi can mow the park in 3 hours and Deshaun can do the same job in 7 hours. How long will it take them to mow the park
if they work together? Round your answer to the nearest tenth and include units.

2.1 hours (2 hours and 6 minutes)

Step-by-step explanation:

The rate of work of Bobbi is ⅓ while for Deshaun is 1/7 hence combined rate will be

⅓+1/7=(7+3)/21=10/21

The equivalent hours is the reciprocal of the above hence 1021/10=2.1 hours

0.1 of an hour is equivalent to 0.1*60=6 minutes

Therefore, the efforts combined will take 2.1 hours or 2 hours and 6 minutes

To draw the graph of linear equation of the form

 y-a=m (x-b)

We will first write it in slope intercept form which is of the form

It will cut x axis and y axis at ,  respectively.

As Euclid postulate States that, Unique equation of line can be Determined by two points, So join these two points. And Infinite number of points lie on a line.
