Question

An aeroplane travels 1264 km on one leg of a journey, which is 38% of the total. How far is the total journey

Answer 1

Answer:

Journey of aeroplane on one leg = 1264km

Journey of aeroplane on both legs = Total journey of aeroplane = 1264*2= 2528km

Now,

38% of total journey = 38 * 2528

100

= ~960 km

Now,

Total journey = 2528 km

Ans. : 1. The 38% of the total is 960km (approx.)

2. The total journey of the aeroplane is far 2528km.

Answer 2

Answer:

cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkenes. Simply put, hydrocarbon cracking is the process of breaking a long chain of hydrocarbons into short ones. This process requires high temperatures.[1]
