问题 While riding a bicycle, a person traveled 5 blocks in 2 minutes. At this rate, how many blocks will the person travel in 16 minutes?
选项 A、8
B、10
C、16
D、32
E、40
答案 E
解析 The correct answer is E. You are given that the person traveled 5 blocks in 2 minutes, which means that the distance traveled in 16 minutes can be found using a proportion. If x represents the number of blocks traveled in 16 minutes, then 5/2 = x/16. Cross-multiply and solve for x, as shown below:
5/2=x/16
2x=80
x=40
