Given data

  efficiency (η) = 65 %

                        = 0.65

  Machine provides (Work done by the machine) = 1300 × 50

                                                                                 = 65000 J

  efficiency (η) = work done by the machine ÷ work supplied to the machine

               0.65 =  65000 ÷ Input work

              Input work = 100000 J

                                = 100 KJ

One way to ensure that the race ends up in a tie is to have the person who lost the original race run a shorter distance before
Vikki [24]

Answer:

The appropriate answer is "72.8 m".

Explanation:

Let the distance be "x".

As per the question, we get

⇒ T_{Mia}=T_{Brandi}

or,

⇒ \frac{x}{13} +\frac{x}{7}=\frac{\80}{10} +\frac{80}{10}

By taking L.C.M, we get

⇒ \frac{20x}{91}=16

By applying cross-multiplication, we get

⇒ 20x=1440

⇒     x=\frac{1456}{20}

⇒        =72.8\ m
