80d = 400 is the equation that relates the number of days d that an athlete spends training when the athlete trains for 400 min given that athlete trains for 80 min each day for as many days as possible. This can be obtained by converting the given statements into algebraic equation.
Find the required equation for the given question:
Here in the question it is given that,
- Athlete trains for 80 min each day,
that is each day the athlete spends 80 min.
- We have to assume the variable d the number of days the athlete spends training.
- Finally we have to find an equation that relates the number of days d that the athlete spends training when the athlete trains for 400 min.
So we can write that,
400 min is the time spent by the athlete
400 min = number of days × time spent by the athlete in one day
400 min = d × 80
⇒ 80d = 400
Hence 80d = 400 is the equation that relates the number of days d that an athlete spends training when the athlete trains for 400 min given that athlete trains for 80 min each day for as many days as possible.
