Answer:
234.93 minutes. Divide by 60 and you get 3 hours almost 4.
Step-by-step explanation:
Answer:
there are no clocks to compare
Step-by-step explanation:
The ball's velocity will be represented by the derivative of its distance function:

Now find the times

for which this is equal to 30, i.e. solve

This has two solutions,

, but only one is positive and falls in the interval
![[0,3]](https://tex.z-dn.net/?f=%5B0%2C3%5D)
. So the velocity reaches 30 cm/s when

.
4m-t=m
Solution: collect d like term's
4m-m=t
3m=t
m=t/3
Answer:
Theyre all correct
