Final answer:
To calculate Adrian's weekly running goal, we use the information that he had run 45% of his goal. By converting this percentage to a decimal and dividing the amount he has run (45) by 0.45, we determine that his total goal is 100 units.
Step-by-step explanation:
To calculate Adrian's weekly running goal, we need to use the information provided that he had run 45% of his goal by Tuesday. This percentage can be represented as a decimal (0.45) in the calculation. Let's denote the total weekly running goal as G. Given that Adrian has run 45% of G, we can express this as:
0.45 × G
The amount run by Adrian so far is the 45% of G, which is given to be 45% of the total goal. Therefore, we have:
0.45 × G = 45 (since Adrian has run 45% of his goal, which quantitatively is 45 units)
To find the total goal G, we divide the amount run (45 units) by the percentage as a decimal (0.45), which gives us:
G = 45 / 0.45
Calculating this, we get:
G = 100
Therefore, Adrian's weekly running goal is 100 units (which could be in miles, kilometers, etc., depending on the units used in his running log).
