A fuelling vehicle finished filling a plane with 12.40 tons of fuel at 10:35. If the fuelling rate is 0.20 ton of fuel per min, at what time did the fuelling start?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
