The direction of motion of the charge
The answer should be 11,460 because the first half-life leaves 50 percent left and the next half-life would leave 25 percent which dates the bones at 11,460 years old.
Answer:
I believe the answer is B.
Answer
given,
tourist travels = 1500 miles
second plane averages 50 miles per hour faster than the first plane.
x = y + 50
The tourist uses the slower plane for the first 500 and the faster plane for the next 1000 miles.
total flying time = 6.5 hours





on solving equation
y = 86.67 mile/hr
x = 86.67 + 50
x = 136.67 mile/hr
They could change but most likely not
