Further explanation

Comparison is an effort to compare two or more objects in terms of shape or size, or number

Proportional Comparisons are comparisons of two or more numbers where one number increases, the other numbers also increase

 Can be formulated

$\frac {x1} {y1} = \frac {x2} {y2}$

 so that if:

 x = 2

 then

 $y = \frac {y} {x} \times \: 2$

 While the reversal value comparison is the comparison of two or more numbers where one number increases, the other number decreases in value

 Can be formulated

 $\frac {x1} {y2} = \frac {x2} {y1}$

so that if:

 x = 2

 then

 $y = \frac {x} {y} \times \: 2$

The time needed for Juwan to park near his grandmother's house took 35 minutes

From parking to her grandmother's house takes 4 minutes to walk

So the total time needed for Juwan to get to his grandmother's house:

35 minutes + 4 minutes = 39 minutes

So one visit takes = 39 minutes away + 39 minutes home = 78 minutes

While the total time spent by Juwan in a week for visiting = 5 hours and 12 minutes

5 hours 12 minutes = (5 hours x 60 minutes) + 12 minutes = 312 minutes

Then a comparison can be made

1 visit = 78 minutes

x visit = 312 minutes

$\frac{1\:visit}{78} =\frac{x\:visit}{312}$

$x\:visit=\frac{1\times\:312\:minutes}{78\:minutes}$

$x\:visit=\boxed{\bold{4}}$

Answer 2

It takes him 35 + 4 = 39 total minutes one way, so it would take him 39 x 2 = 78 minutes for 1 round trip.

convert 5 hours and 12 minutes into minutes: 1 hour = 60 minutes.

5 hours x 60 minutes = 300 minutes.

300 + 12 = 312 total minutes for the week.

Divide total minutes by minutes per round trip:

312 / 78 = 4 round trips total
