Sophia trains with her friend Aisha on a 5-kilometer trail near their school.
Aisha starts running right after school and runs an average of one kilometer in seven minutes.
Sophia leaves 10 minutes later and runs at a steady pace shown in the table below.
Write each function as a linear equation where x is the number of kilometers and y is the number of minutes.
Who runs faster? Explain.

Yes of course i will indeed you with your problem.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
