    Hi I need help with this,

    Box A and Box B contain the same number of apples.The number of red apples in box A is 2/3 of that in Box B. The number of green apples in Box B is 1/4 of that in Box A. What fraction of the apples in Box B are red?

    The answer said it is 9/10 but my answer is 3/4. Can you explain why it is 9/10. Thanks.~

    Tom started running from Point X in a clockwise direction and John started running from Point Y in an anti-clockwise direction on a 400 m track. They started running from directly opposite ends of the track at the same time. Tom ran at an average speed of 160m/min while John ran at an average speed of 200m/min. How far would Tom have run by the time they passed each other the second time on the track? Give your answer as a mixed number in the simplest form.
