How to put this an equation

NISA [10]

<span><span>40. </span>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.
