Answer: B. hours
Step-by-step explanation:
Let us closely look at the varible <em>t</em> it gives, the one we are looking at units for. "t stands for the amount of time the workers have left to clean the windows"
"t stands for the amount of <u>time</u> ..."
The only unit they give that represents time is hours, meaning the answer to your question is:
B. hours
Answer:
Step-by-step explanation:
i would say is that every 20 mins its 80 that means every hour its 240 so just multiply it by 8 idk if its right but thats what i would do
Answer:
t = 11 min
and
t = 18 min
Step-by-step explanation:
When we have unidimensional motion, the sign of the velocity defines the direction.
So we could say that a positive velocity like:
v = 4ft/min
Means that you are moving to the right with a speed of 4 feet per minute.
And a negative velocity like:
v = -3 ft/min
means that you are moving to the left with a speed of 3 feet per minute.
Then the bug changes direction when the velocity changes of sign.
In the graph, we can see that the velocity changes of sing in two points, these points are:
t = 11 min
and
t = 18 min
