Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in 3 hours and 6 minutes?
Veronika [31]

Answer:

He will bike <u>26.87 miles</u>.

Step-by-step explanation:

Given:

Jordan bikes at a speed of 8 2/3 mph.

Now, to find the distance he will bike in 3 hours and 6 minutes.

<u><em>Speed</em></u> =  8\frac{2}{3}=\frac{26}{3}\ mph.

<u><em>Time</em></u> = 3 hours and 6 minutes

         = 180+6=186\ minutes.

As, 60 minutes = 1 hour.

         = \frac{186}{60} =3.1\ hours.

So, to get the distance we put formula:

Distance=speed\times time

Distance=\frac{26}{3} \times 3.1

Distance=\frac{80.6}{3}

Distance=26.87\ miles.

Therefore, he will bike 26.87 miles.

seraphim [82]

Answer:

30 milkshakes and 40 root beer floats

Step-by-step explanation:

Set up a system of equation (r is root beer and m is milkshake)

2.75r+6m=290

m+10=r

Substitute

2.75(m+10)+6m=290

2.75m+27.5+6m=290

8.75m=262.5

m=30

Now plug in 30 and solve for r

30+10=40
