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 26.87 miles.

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.

Speed = $8\frac{2}{3}=\frac{26}{3}\ mph.$

Time = 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
