If it takes Annette 13 minutes to jog a yards and she continues at that rate for b feet, how long will it take Annette to complete the b feet? (1 yard = 3 feet)
A. 13a/(3b)
B. 39b/a
C. 13b/(3a)
D. 13b/a
E. b/(39a)
Another approach: assign values.
Annette takes 13 minutes to jog\(a = 2\) yards.
Rate:\(\frac{2yds}{13mins}\)
Rate in feet (multiply yards by 3): \(\frac{2yds}{13mins}=\frac{(2*3)}{13mins}=\frac{6ft}{13mins}\)
