Question

What is the speed of the object between 60 to 70 seconds?

Answer 1

We have that the speed of the object between 60 to 70 seconds

$V=\frac{d}{65}$

From the question we are told

The speed of the object between 60 to 70 seconds

Generally the equation for Average speed   is mathematically given as

$V=\frac{d}{t}$

Where

$t=\frac{60+70}{2}\\\\t=65seconds$

Therefore

$V=\frac{d}{65}$

In conclusion

The speed of the object between 60 to 70 seconds

$V=\frac{d}{65}$
