Heather and Matthew walk with an average velocity of 0.98 m/s eastward. If it tskes them 34 min to walk to the store, what is their displacement?

1999.2

Sorry for being 12 years late but the answer is 1999.2 😂

To find the displacement of Heather and Matthew, we need to find the distance they traveled and the direction they traveled in.

First, let's find the distance they traveled. We know their average velocity is 0.98 m/s, and they walked for 34 min. To convert the time to seconds, we multiply 34 min by 60 sec/min:

34 min * 60 sec/min = 2040 sec

Now, we can find the distance they traveled by multiplying their average velocity by the time:

Distance = Velocity * Time
Distance = 0.98 m/s * 2040 sec

Calculating this, we get:

Distance ≈ 1999.2 meters

So, Heather and Matthew traveled approximately 1999.2 meters.

Now, to find their displacement, we need to consider direction. Since they walked eastward, their displacement will also be eastward. Therefore, their displacement is +1999.2 meters eastward. Note that we use the positive sign to indicate the eastward direction.

Therefore, the displacement of Heather and Matthew is +1999.2 meters eastward.

34 min (60 s/min) = 2040 seconds

.98 m/s (2040s) = 1836 meters
