Yael worked out at a gym for 2 hours.her workut consisted of stretching for 21 minutes,jogging for 45 minutes,and lifting weights for the remaining amount of time.what percentage of yaels workout was spent lifting weights

Respuesta :

There are 60 minutes in one hour. So to find out how many minutes there are in 2 hours just do 2x60=120. After you find that out do 120-21-45= 54. Now we know how many minutes he worked out for. So now we do (54÷120)x100=45. The percentage of Yaels workout is 45%
