Step-by-step explanation:
Given that :
Objective is to compete in a 5km road race ;
Reduction in race tone per month = 15 seconds
Rqce comes up in 3 months
Total change in race time he hopes to achieve :
1. What integer represents the change in race time Riley wants to achieve each month ; 15 seconds
2. What integer represents the number of months she will train?
She will train for 3 months ; 3 months
Write a multiplication expression that can be used to find the total change in time.
Change in race time * number of month she will train
15 seconds * 3 months = 45 seconds
Let initial race time = (t)
t - 15(month in which race comes up).
t - (15-3) = t - 45
