For every 10 minutes of lifting weights in the gym, Albert does 15 minutes of cardio. On Monday, he spent 1 hour and 15 minutes in the gym. How long did he spend doing cardio?
answer plzzzzzzzzzzzzzzzzzz
got it nevermind
To find out how long Albert spent doing cardio, we need to first determine the total time he spent in the gym.
On Monday, Albert spent 1 hour and 15 minutes in the gym. Since there are 60 minutes in an hour, we can convert 1 hour to 60 minutes. Therefore, Albert spent a total of 60 + 15 = 75 minutes in the gym.
According to the given information, for every 10 minutes of lifting weights, Albert does 15 minutes of cardio. So, we can determine how many sets of 10 minutes he did by dividing the total time spent in the gym by 10 minutes.
75 minutes ÷ 10 minutes = 7.5 sets
Since Albert can't do a fraction of a set, we can round down to the nearest whole number to find out how many complete sets of 10 minutes he did. In this case, Albert did 7 sets of 10 minutes.
Now, we can calculate how long he spent doing cardio by multiplying the number of sets by the time spent per set.
7 sets × 15 minutes/set = 105 minutes
Therefore, Albert spent 105 minutes doing cardio on Monday.
