20+6/10+15/100-43/10
= [20(100) + 6(10) + 15 - 43(10)]/100
= [2000 + 60 + 15 - 43]/100
= [2075 - 43]/100
= 2032/100

The speed of the helicopter is 100mile/h with respect to air.
Give v1 a chance to be the speed of the helicopter
What's more, v2 be the speed of the breeze which has greatness b
v1 = 100 cos 60o i + 100 sin 60o j
= 50i + 50√3j
What's more, from the other idea
v2 = an i
the resultant is given by
v1 = v1+v2
=(50+a)i + 50√3j
As given in the inquiry , the helicopter lands 45* east of north because of the breeze, at that point x part will be equivalent to y segment
50+a = 50√3
a = 50(√3-1)
a = 36.6 miles/hr
Cheers!!

The process in which a volatile liquid is first vaporised at its boiling point and the vapours are condensed to get back the liquid in pure form is called distillation.
If the difference in boiling points of the liquids in the mixture is less than 250C the method of fractional distillation is used to separate them.
Fractional distillation method is same as simple distillation except that in the apparatus a fractionating column is fitted in between the distillation flask and the condenser.
It makes the appratus more efficient . A fractionating column is a wide tube packed with glass beads, which provides a larger surface area of cooling. Vapours of liquid having higher boiling point get condensed on the surface of these beads, while the vapours of lower boiling point liquid pass on upwards. Length of the column also increases the efficiency of the process.
Example: In an oil refinery, the different fraction of petroleum products are separated by fractional distillation of crude petroleum.

Burning of coal in absence of air to obtain some useful constituents is called destructive Distillation. Following constituents are obtained from this process :
(i) Coke : It is a hard porous substance which is almost the purest form of carbon. It is used in manufacture of steel and in extraction of many metals.
(ii) Coal-tar : It is a black liquid with unpleasant smell. It is a mixture of about two hundred substanes which are very useful in our day to day life. They are used in drugs, plastics, paints, photographic materials, synthetic dyes, roofing materials, perfumes, explosives etc. Insect repellants like naphthalene is also obtained from it. Earlier, it was also used for surfacing of roads.
(iii) Coal gas : This gas is also obtained during destructive distillation of coal. It is used as fuel in coal processing plants and in various other industrial units situated near coal processing plants. Coal gas was used by the Americans and the Britishers for street lighting.
