Brandi jogged 2 1\2 miles in 30 minutes. sharma jogged 3 1\2 miles in 3\4 hour. who jogged at slower rate

The speed of Sharma is slower than the speed of Brandi

I.e ∵   4.67 miles per hour   5 miles per hour

      ∴  

Step-by-step explanation:

Given as :

The distance cover by Brandi = = 2 =

The Time taken by Brandi for jogging =   = 30 minutes = hour

Let the speed of Brandi = =

or,   =  }{\textrm   }" alt="D_1" />  }{\textrm   }" />

Or.   =

∴   = 5 miles per hour

Again

The distance cover by Sharma = = 3 =

The Time taken by Sharma for jogging =   = hour

Let the speed of Sharma = =

or,   =  }{\textrm   }" alt="D_2" />  }{\textrm   }" />

Or.   =

∴   = = 4.67 miles per hour

Now, ∵   4.67 miles per hour   5 miles per hour

         ∴  

So, Sharma jogged at slower late

Hence The speed of Sharma is slower than the speed of Brandi Answer

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
