Ответ:
Percentage of increase in distance of running each day = 15%
Let us assume that the day on which Rudy will run 4 km = x
Then
2 + 0.15x = 4
0.15x = 2
x = 2/0.15
= 13.3
From the above deduction we can conclude that Rudy will run more than 4 km on the 14th day or on Sunday. I hope the procedure is clear enough for you to understand.
