Correct Answer: A
Explanation:
One hour after Yasmin started walking from X to Y, a distance of 45 miles; Babar started walking along the same road from Y to X. If Yasmin’s walking rate was 3 miles per hour and Babar’s was 4 miles per hour, how many miles had Bob walked when they met?
One hour before Babar started, Yasmin had traveled distance = 3
The remaining distance = 45 - 3 = 42
Speed of Yasmin = 3 and speed of Babar = 4
Distance travelled by Babar = × 42 = 24
