Last Wednesday, two friends met up after school to read the book they were both assigned in Literature class. Kelly can read 2 pages per minute, and she had already read 90 pages. Susan, who has a reading speed of 4 pages per minute, had read 50 pages. Eventually, they had read the same number of pages. How long did that take? How many pages had each of them read? Help fast please

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 )
