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.
We can start by setting up a proportion to relate the amount of time the athlete trains each day with the total number of days they train.
Let d be the number of days the athlete spends training.
Since the athlete trains for 115 min each day, the total amount of time they train can be expressed as 115d.
We are given that the total amount of time the athlete trains is 690 min.
Therefore, we can set up the equation:
115d = 690
Simplifying the equation, we divide both sides by 115:
d = 6
Therefore, the equation that relates the number of days d that the athlete spends training when they train for 690 min is:
115d = 690
Let's set up the equation:
Total time spent training = Time spent per day × Number of days
Given that the athlete trains for 115 minutes each day, we have:
Total time spent training = 115 × Number of days
Since the problem states that the athlete trains for 690 minutes, we can substitute that value into the equation:
690 = 115 × Number of days
Therefore, the equation that relates the number of days (d) that the athlete spends training when training for 690 minutes is:
690 = 115d
