Question

图中显示了骑车人阿尔韦托（Alberto）和比约恩（Bjorn）骑行的英里数。四小时后，阿尔韦托大约比比约恩多骑了多少英里？

The diagram shows the miles traveled by bikers Alberto and Bjorn. After four hours, about how many more miles has Alberto biked than Bjorn?

$15$

$20$

$25$

$30$

$35$

读出 $4$ 小时时两人的距离

Read both distances at $4$ hours

用阿尔韦托的距离减去比约恩的距离

Subtract Bjorn’s distance from Alberto’s

从图中可见， $4$ 小时后阿尔韦托骑了 $60$ 英里，比约恩骑了 $45$ 英里。

两者的距离差是 $60 - 45 = 15$ 英里。

所以正确答案是 A。

Looking at the graph, we have that Alberto has biked $60$ miles and Bjorn $45$ miles after $4$ hours.

The difference between the two distances is $60 - 45 = 15$ miles.

Thus, A is the correct answer.
