Question

Calculate the total distance you traveled, if:

You left home at 10 a.m. and walked 500 m to a friend's house. At 11, you
all drove 5 km to the mall.
At 1:30, your friend drives you 4 km to your house. The total distance you
traveled, round trip, is

Answer 1

9.5km

Step-by-step explanation:

To solve this problem, we add the distances given together.

The distance is the sum of the length of path covered. It is a scalar quantity and has only magnitude but no directional attribute.

Distance walked to friend's house = 500m

Distance to mall = 5km

Since 1000m = 1km, 5km will be 5000m

Distance back to house = 4km

In m, this gives 4000m

So;

Total distance covered = 500m + 5000m + 4000m = 9500m

Since 1000m = 1km;

Then, 9500m will given 9.5km
