calculate the number of runners who finished the race in less than 4 hours.

Question

if 8000 runners ran a race and 3/16 of the runners finished in less than 4 hours and 0.65 of the runners finished the race in 4 or more hours, calculate the number of runners who finished the race in less than 4 hours.

Answer 1

if 8000 runners ran a race and 3/16 of the runners finished in less than 4 hours...calculate the number of runners who finished the race in less than 4 hours.

 

8000 x 3/16 = 1500

 

But... 3/16 = 18.75%, and .65 = 65%, and 65% + 18.75% = 83.75%, so, what happened to the other runners???  Did they fail to finish???
