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.

Question

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.
