Two engineering teams excavate a 675m-long tunnel at the same time, and each works from one end to the other. It takes 25 days to get through. Team A excavates 12.6m per day. How many meters does team B excavate per day? (solution by equation method)
两个工程队同时开凿一条长675m的隧道，各从一端相向施工，25天打通，甲队每天开凿12.6m，乙队每天开凿多少米？(用方程方法解答)
<gadget id="calculator">675 - 320</gadget>
<output>355</output>

<gadget id="calculator">355 / 25</gadget>
<output>71/5 = around 14.2</output>

<result>71/5 = around 14.2</result>
