You are 36 miles from a friend. you both start riding your bikes toward each other at the same time. you travel 15 miles per hour and your friend travels 3 miles slower. how far will you travel before you meet your friend?

I wil have traveled 20 miles by the moment I meet my friend

Step-by-step explanation:

Hi

We are going to use de following formula

In my case speed will be positive, so and , For my friend speed will be negative, so and . Then we can build two equations

(1)

(2)

By replacing (1) in (2)

Multiplying both sides by 5

So I wil have traveled 20 miles by the moment I meet my friend.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
