Answer:

51.69 hours (see explanation)

Step-by-step explanation:

This question is simple once you break it down:

84 boxes in 312 hours is a rate, so it can be shown in fraction form:

84 boxes / 312 hours

Now to figure out how long it takes to unpack those 192 boxes, just multiply:

192 x 84/312

(192 x 84) / 312

16128 / 312

Now, just divide the numbers:

16128 ÷ 312 = 51.69 hours

Answer:

I don't know if you have ever watched Stranger Things, but this question makes me thing of one of the main characters in season 2: Bob Newbie... Lolz my fave....

anyways, if Bob had to pack 192 boxes but he had already packed 84 boxes in a time of 312 hours... (do you mean 3.12? because there is not 312 hours in a day...) let x be the length of time it takes to pack the remaining boxes. and create a formula like this: 192/84 = 3.12/x

to find x, cross multiply:

192x=84(3.12) = 262.08

Then isolate x

192/x = x

what you do to one side of the equation, do to the other, so divide 262.08/192=1.365

then depending on the situation, round 1.365 by whatever your assignment says to do.

"Easy peasy, right?" -Bob Newbie -Stranger Things 2  Sorry, i just had to do that reference...

So if i was correct on how to solve this, it should have taken Bob 1.365 hours to pack up the remaining boxes.

This is just how I would first think of solving this, but i'm no expert. all i can say is good luck. :)

Bill and Joe leave their house at the same time heading in opposite directions. If Bill is driving three times faster than Joe a
Arisa [49]

The problem statement gives you the relationship between their speeds, and it gives you information you can use to find their total speed. You solve this by finding the total speed, then the proportion of that belonging to Bill.

The total speed is (120 mi)/(3 h) = 40 mi/h.

The speed ratio is ...

... Bill : Joe = 3 : 1

so the speed ratio Bill : Total is ...

... 3 : (3+1) = 3:4.

Bill's speed is (3/4)×(40 mi/h) = 30 mi/h.
