Question

As you walk to the grocery store you walk 800m North, 600m East and 200m South at a speed of 2m/s. what is the total time it will take you to get to the store.
A. 800 s
B. 600 s
C. 400 s
D. 200 s

Answer 1

To find the total time taken to walk to the grocery store, we first calculate the total distance walked.

1. The distances walked are:
- North: 800 m
- East: 600 m
- South: 200 m

2. The total distance can be calculated as:
\[
\text{Total Distance} = 800\, \text{m} + 600\, \text{m} + 200\, \text{m} = 1600\, \text{m}
\]

3. The speed of walking is given as 2 m/s. We can use the formula for time:
\[
\text{Time} = \frac{\text{Distance}}{\text{Speed}}
\]

4. Substituting the total distance and speed into the formula:
\[
\text{Time} = \frac{1600\, \text{m}}{2\, \text{m/s}} = 800\, \text{s}
\]

Thus, the total time it will take you to get to the store is **800 seconds**.

The answer is **A. 800 s**.
