Reagan and Nathan are 40 miles apart on a bike trail when they start pedaling toward each other on their b bicycles. Reagan ride

irinina [24]

Answer:

They meet in 2.22 hours.

Step-by-step explanation:

We can find the time at which Reagan and Nathan meet by equaling the time as follows:

$v_{R} = \frac{x_{R}}{t}$

$x_{R} = v_{R}t$ (1)

$v_{N} = \frac{x_{N}}{t}$

$x_{N} = v_{N}t$ (2)

Where R is for Reagan and N for Nathan.

Knowing that:

$x_{R} + x_{N} = 40 mi$

By adding equations (1) and (2) we have:

$x_{R} + x_{N} = v_{R}t + v_{N}t$

$t = \frac{x_{R} + x_{N}}{|v_{R}| + |v_{N}|} = \frac{40 mi}{8 mi/h + 10 mi/h} = 2.22 h$

Therefore, they meet in 2.22 hours.

I hope it helps you!

Karla has spent $42 on food. She bought milk, cheese, and meat. The milk cost half as much as the cheese and the meat cost four

Alina [70]

M = milk

C= cheese

X=meat

milk = 0.5c

meat = 4c

cheese = 1c

C= 42/5.5 = 7.64

X = 7.64 x 4 = 30.56

M =7.64 * 0.5 = 4.67

30.56 + 3.82 + 7.64 = approximately $42
