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!
