How to put this an equation

(an athlete trains for 115min 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 690min.

Verified Answer :

40.   115m
= An athlete trains per day

690m = total minutes of athlete’s training

d = number of days

=> 115(d) = 690


Now, the equation would be, 115 minutes per day to be multiplied by d or the
number of days to get 690minutes in all.

=>  690 / 115 = 6

=> 115 (6) = 690

d = 6


Therefore, an athlete trains 115 minutes in 6 days to get the total of 690
minutes in all.
