Cos x = 15÷17
because cos is adjacent side over hypotenuse.
If it is just babysitting and yard work, then the obvious answer is yard work. Of it has other answers, then it would be a camp counselor. Also, never say it's not an exam, it would make people suspicious.
Step-by-step explanation:
Let running speed = x.
So, cycling speed = 2x.
Total distance traveled = 20 + 25 = 45km
Time taken running = 20/x
Time taken cycling = 25/2c
Total time taken = 5 hours
So, 5 = 20/x + 25/2x
Solving this equation for x gives:
10x = 65. Thus x = 6.5
Since cycling speed = 2x, cycling speed = (6.5)(2)
So cycling speed is 13 km/h.
