Suppose the English could drill the Channel in 6.2 years, then they drill with speed 
km per year, where L is the length of the English Channel. If the French could drill in 5.8 years, then their speed of drillling is 
km per year.
Together their speed will be
.
If they drill together, they will spend
years.
Answer: it would have taken nearly 3 years.
you would need to add the fraction
1.5 times 10 to the -8th power
2l + 2w = 16
2(l+ w) = 16 Divide both sides by 2
l + w = 16/2
l + w = 8
So for example the length l could be 5 and the width could be 3.
Length could be 5.
Answer:
6/5
