If we add four times the age of Dakota four years from now to five times her age five years from now we get ten times her current age.
How old will Dakota be three years from now?
If the current age of Dakota is x
4(x+4) + 4(x+5) = 10x
Thus x=41 years
After three years, Dakota will be 41+3 = 44 years
John was gifted a new Hayabusa. He drove x miles at 55mph. Then he drove x+20 miles at 40mps. He drove his bike for 100 minutes. How much distance did he travel?
t1 + t2 = 100 minutes = 100/60 hours
t1 = x/55
t2 = (x+20)/40
x/55 + (x+20)/40 = 100/60
x = 1540/57
Thus, Total distance = x + (x+20) = 4220/57 miles = 74 2/57 miles
