Answer: It traveled 0.06172 km.
Step-by-step explanation:
Given: Speed of block = 4 m/s
Time taken by block = 15.43 s
To calculate: Distance covered by it in km.
We know that,

So distance covered by block = 
= 
Since 1 kilometer = 1000 meters.
So,

Hence, it traveled 0.06172 km.
Answer: $20.82 per hour
Step-by-step explanation:
Well, the common denominator of6 and 15 would be three so you would get 2 and 3
the common denominator of 30 and 80 would be 10 and it would equal 3 and 8
A=p (1+rt)
A future value ?
p Principle 900
R interest rate 0.06
T time 9/12
A=900×(1+0.06×(9÷12))
A=940.5
