Answer:

A) The sum or difference of the numbers is [tex]\frac{1}{2}[/tex] , option B

B)  The total distance cover by Tom is 1 [tex]\frac{2}{35}[/tex] miles

C)  The longer duration of Tom on Monday than Tuesday is [tex]\frac{5}{8}[/tex] hours , option B              

Step-by-step explanation:

Given as :

A) The given benchmarks as 0 , [tex]\frac{1}{2}[/tex] , 1

From the given number , the mid number is  [tex]\frac{1}{2}[/tex]

So, The sum of the number = 0 +  [tex]\frac{1}{2}[/tex]

I,e The sum of the number =   [tex]\frac{1}{2}[/tex]

And The difference of number = 1 -  [tex]\frac{1}{2}[/tex]

Or, The difference of number =   [tex]\frac{2 - 1}{2}[/tex]

Or, The difference of number = [tex]\frac{1}{2}[/tex]

Hence The sum or difference of the numbers is [tex]\frac{1}{2}[/tex]  Answer

B) The distance cover by Tom on Monday = [tex]\frac{1}{5}[/tex] miles

The distance cover by Tom on Tuesday = [tex]\frac{6}{7}[/tex] miles

So, The total distance cover = The distance cover on Monday + The distance cover on Tuesday

I.e  The total distance cover =  [tex]\frac{1}{5}[/tex] miles +  [tex]\frac{6}{7}[/tex] miles

Now, taking LCM

Or, The total distance cover =  [tex]\frac{7 + 30}{35}[/tex] miles

Or, The total distance cover =  [tex]\frac{37}{35}[/tex] miles

I.e The total distance cover =  1 [tex]\frac{2}{35}[/tex] miles

Hence The total distance cover by Tom is 1 [tex]\frac{2}{35}[/tex] miles Answer

C) The time period of Tom reading on Monday = [tex]\frac{7}{8}[/tex] hours

The time period of Tom reading on Tuesday = [tex]\frac{2}{8}[/tex] hours

The longer duration of Tom on Monday than Tuesday = x hours

So, x =   The time period of Tom reading on Monday -  The time period of Tom reading on Tuesday

I.e x = [tex]\frac{7}{8}[/tex] hours - [tex]\frac{2}{8}[/tex] hours

∴ x = [tex]\frac{7 - 2}{8}[/tex] hours

I,e x = [tex]\frac{5}{8}[/tex] hours

So, The longer duration of Tom on Monday than Tuesday = x =  [tex]\frac{5}{8}[/tex] hours

Hence  The longer duration of Tom on Monday than Tuesday is [tex]\frac{5}{8}[/tex] hours   . option B  Answer
