An athlete trains for 115 min each day for as many days as possible. Write an equation that relates the number of days d that the athlete spends training when the athlete trains for 690 min.
d = 690/115
Let's use the equation:
d = 690 / 115
Where:
d = Number of days the athlete spends training
690 = Total minutes the athlete trains
115 = Minutes spent training each day
Now we can solve for d:
d = 690 / 115
d ≈ 6
Therefore, the athlete will spend approximately 6 days training when training for a total of 690 minutes.
