Question

UpStudy AI · Accepted Answer

Molly walks 3 miles east to Raven's house and then 4 miles north to the library. The total distance she walks is the sum of these two distances.
The total distance $$D$$ that Molly walks is given by:
$$ D = 3 \text{ miles} + 4 \text{ miles} = 7 \text{ miles} $$
To find the time $$T$$ spent walking, we use the formula:
$$ T = \frac{D}{S} $$
where $$S$$ is her speed (3 miles per hour). Thus:
$$ T = \frac{7 \text{ miles}}{3 \text{ miles per hour}} $$
Calculate the value by following steps:
- step0: Calculate:
  $$\frac{7}{3}$$
Molly spends approximately $$ 2 \frac{1}{3} $$ hours walking, which is about 2.33 hours. Therefore, the closest answer choice is C: 3 hours.
