ann and bob drive separately to a meeting. ann ' s average driving speed is greater than bob ' s avergae driving speed by one - third of bob ' s average driving speed, and ann drives twice as many miles as bob. what is the ratio r of the number of hours ann spends driving to the meeting to the number of hours bob spends driving to the meeting?

ann and bob drive separately to a meeting. ann ' s average driving speed is greater than bob ' s avergae driving speed by one - third of bob ' s average driving speed, and ann drives twice as many miles as bob. what is the ratio r of the number of hours ann spends driving to the meeting to the number of hours bob spends driving to the meeting?
divide(const_2, add(const_1, divide(const_1, const_3)))
"say the rate of bob is 3 mph and he covers 6 miles then he needs 6 / 3 = 2 hours to do that . now , in this case the rate of ann would be 3 + 3 * 1 / 3 = 4 mph and the distance she covers would be 6 * 2 = 12 miles , so she needs 12 / 4 = 3 hours for that . the ratio r of ann ' s time to bob ' s time is 3 : 2 . answer : b ."
