Question

An object travels 100 m in 10 s and then another 200m in 5s
What is the average speed of the object?​

Answer 1

$\huge \mathtt{\red{A}\pink{n}\blue{s}\purple{w}\green{e}\pink{r}}$

$\sf{Average \: speed = \frac{Total \: distance}{Total \: time} }$

$\large\sf{ = \frac{300}{15} = 20}$

So average speed is 20m/s
