In the same bus-stop trip, the father walks straight to the stop in 34 s while his daughter runs a varied path at 3.5 m/s the whole time. If she had instead run in a straight line at that same speed for that same 34 s, how far beyond the 75 m bus stop would she have gone?
A44 m
B75 m
C119 m
D163 m
Answer & Solution
Correct answer: A. 44 m
1. In 34 s at 3.5 m/s in a straight line, she would cover 3.5 x 34 = 119 m.
2. The bus stop is only 75 m away in a straight line.
3. She would overshoot it by 119 m - 75 m = 44 m.
