Final answer:
Joshua needs to run an additional 71.5 miles to reach his goal.
Step-by-step explanation:
To find out how many more miles Joshua needs to run to reach his goal, we first need to calculate how many miles he has already run. We are told that by Thursday, he ran 45 percent of his goal. So we can find the number of miles he has run by multiplying his goal of 130 miles by 45 percent.
45 percent of 130 miles is (45/100) * 130 = 0.45 * 130 = 58.5 miles.
Since Joshua ran 58.5 miles by Thursday, he still needs to run the remaining distance to reach his goal of 130 miles. This can be found by subtracting the miles he has already run from his goal:
130 miles - 58.5 miles = 71.5 miles.
Therefore, Joshua needs to run an additional 71.5 miles to reach his goal.
