    i think you would first need to get an average because you want an estimate so you would add all 3 speeds and divide by 3 and then take that value divide it into 460.which would be about 10 minutes

    find the average words per minute, you can do that by adding up the three scores and dividing that by three. The once closest to the average is a good estimate. then to find for each time, take the average and multiply it by the number of minutes

    Divide 460 by the average typing rate. \[\frac{460}{\frac{1}{3} (41+48+50)} = 9.928.. \]
