+ Application When building the Chunnel, the English and French each started drilling on opposite sides of the English Channel. The two sections became one in The French used more advanced drilling machinery than the English. Suppose the English could drill the Chunnel in 6.2 years and the French could drill it in 5.8 years. How long would it have taken the two countries to drill the tunnel?
