Question

an object travels 40m in 4 sec and 30m in 3sec .what is the averge speed of the object ?​

Answer 1

Answer:

10

Explanation:

because when we add speed 1 and speed 2 and then divide by 4+3=7 then ot gives us 10m/h

Answer 2

Answer:

Distance covered by object in 4 second=40m

Distance covered by object in 3 second=30m

Hence,distance covered by object in

7 second=30m+40m

=70m

So, Average speed =Distance covered by object divided by total time taken to cover that distance

=70÷7

=7 m per second

This is the average speed.
