Question

.An object travels a distance of 12.8 m in 15 seconds. What is its average velocity
​

Answer 1

Answer:

So you need to calculate how far the object goes

by travelling with the speed of 10 m/s (note the notation - small ‘m’ for meter) for 15 s

and by travelling travelling with the speed of 15 m/s for 10 s.

You just calculated the distance traveled. You calculated it in two parts; the total distance is what matters here.

Then, the time it took to travel was given in your assignment. It’s given in two parts, but you can do the math.

Now you have all the ingredients for success. Just divide and conquer!
