Answer:
15 seconds
Step-by-step explanation:
Simply assume that total length to be covered be 'L'.
Now , 
of total length L is covered in time 
.
We know distance traveled =speed×time
Let Object's velocity be V
Using this
Thus, velocity in terms of total length is
Now,
To cover total length L time needed is
Time taken =15 seconds

Answer:
we know that, Volume of cube=a³
Let volume of 1st cube be 2x with side a and other be x with side A (according to given ratio)
Step-by-step explanation:
ATQ: 2x=a³ and, x=A³
a=³√2x and, A=x
we know that, surface area of cube is 6a²
Thus, surface area of 1st cube = 6(³√2x)²
= 6³√4x²
Surface area of 2nd cube=6(x)²=6x²
Ratio of S.A=(6³√4x²)÷(6x²)
Ratio of S.A=³√4:1
