Final answer:
Darnell will have to run for at least 40.33 days to reach his goal. The minimum number of days he needs to run is 41 days.
Step-by-step explanation:
To find the minimum number of days, d, that Darnell will have to run to reach his goal, we can use the formula:
d = (goal distance - already jogged distance) / average distance per day
Substituting the given values:
d = (150 - 29) / 3
Simplifying the expression:
d = 121 / 3
So, Darnell will have to run for at least 40.33 days to reach his goal. Since he cannot run for a fractional number of days, the minimum number of days he needs to run is 41 days.
