A jet travels 584 miles in 4 hours. At this rate how far could the jet fly in 13 hours?what is the rate of speed of the jet

ankoles [38]

Answer:

The speed at which jet travel is 44.92 miles per hour

The distance cover at 44.92 mph is 583.96 miles .

Step-by-step explanation:

Given as :

The distance cover by jet = d = 584 miles

The time taken b the jet to cover 584 miles = t = 13 hours

Let The speed at which jet travel = s

So, Speed = $\dfrac{\textrm distance}{\textrm time}$

or, s = $\dfrac{\textrm d}{\textrm t}$

Or, s = $\frac{584}{13}$

∴ s = 44.92 mph

So , The speed at which jet travel = s = 44.92 miles per hour

Now, At The speed of 44.92 mph

Let The distance cover at this speed = d' miles

And for the distance of d' , the time taken= 13 hours

Now, Distance = Speed × Time

So, d' = 44.92 mph × 13

Or, d' = 583.96 miles

So, the distance cover at 44.92 mph = d' = 583.96 miles

Hence The speed at which jet travel is 44.92 miles per hour

And The distance cover at 44.92 mph is 583.96 miles . Answer

HOW SHOULD I DO WORK... HELP!!!!!

Angelina_Jolie [31]

Answer: You should create number line since it's a inequality question, so it would make sense. But In my opinion I don't think you need to show your work unless it tells you to. So that's why I'm telling you that you can show work, which is by making a number line.

* I hope this helps:) Mark me the brainliest:)!!
