Question

An object travel 20m in 10s and 10m in 5s find its average speed

Answer 1

Average speed=total distance/total time
=20+10/10+5
=30/15
=2m/s

Therefore the average speed the object is 2m/s

There’s your answer mate

Hope it helped!!!

Answer 2

Given :

• Distance travelled by the object in 10s is 20 m
• Distance traveleld by the object in 5s is 10m

To find :

• The average speed of the object

Solution :

The ratio bewteen the total distance travelled to the total time taken is known as average speed.

$\boxed{ \rm{average \: speed = \frac{total \: distance}{total \: time} }}$

By substituting the values we have ,

$: \implies \rm \: average \: speed = \frac{20 \: m + 10 \: m}{10 \: s + 5 \: s} \\ \\ : \implies \rm \: average \: speed = \frac{30 \: m}{15 \: s} \\ \\ : \implies \rm \: average \: speed = 2 \: m {s}^{ - 1}$

Hence , The average speed of the object is 2 m/s.
