A climber trekked to the top of Mount Everest, elevation 29,035 ft. From a starting point of 24976 ft. In a time of 15 hr, 35 min. Determine the average rate of climb in:(a) miles per minute

The average rate of climb in miles per minute is 8.2x10⁻⁴ miles/min.

Explanation:

The average rate can be calculated as follows:

Where:

: is the initial height = 24976 ft

: is the final height = 29035 ft

: is the initial time = 0

: is the final time = 15 hr, 35 min = 935 min      

Then, the average rate of climb in miles per minute is:

Therefore, the average rate of climb in miles per minute is 8.2x10⁻⁴ miles/min.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
