.5 + .5d = 7.5
Solve for d.
Solve for d.
is
.5 , 1.5 3.0 , 5.0, 7.5 on day 5
of course this is an arithmetic sequence with d = .5
.5 + (n-1).5
John currently runs 0.5 miles per day, and he wants to increase it by 0.5 miles each day until he reaches 7.5 miles.
Let's set up an equation:
0.5 miles/day * X days = 7.5 miles
Here, X represents the number of days it will take.
We need to isolate X to find the answer. To do that, we'll divide both sides of the equation by 0.5 miles/day:
X = 7.5 miles / 0.5 miles/day
Simplifying this, we get:
X = 15 days
Therefore, it will take John 15 days to reach a total distance of 7.5 miles if he increases his daily run by 0.5 miles.
