The many different hydrocarbon compounds found in petroleum can be separated in a process called A-Fractional distillation
B-Combustion
C-Condensation
D-Nuclear reaction

Any idea

Fractional distillation

Explanation:

Fractional distillation is the use of distillation to separate a liquid mixture into different parts (fractions) that differ in boiling point. The substances in crude oil have different boiling points, so they can be separated by fractional distillation.

increases it

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
