Answer:
It was <u>2.00 p.m.</u> when Clara finished the hike.
Step-by-step explanation:
Given:
Clara hiked to the top of a mountain. She started the hike at 10:30 A.M.
It took 2 hours and 45 minutes to get to the top of the mountain and 45
minutes to hike back down.
Now, to find the time Clara finished the hike.
Clara started hike = 10.30 a.m.
It took 2 hours and 45 minutes to get to the top of the mountain.
So, we add the 2 hours and 45 minutes to 10.30 a.m:
As, 1 hour = 60 minutes.
Now, to add the 45 minutes he took to hike down:
Therefore, it was 2.00 p.m. when Clara finished the hike.
All solutions are colloid because the mixtures are uniform in the ratio of combination of substances.

z=14
Step-by-step explanation:
OK the problem is focusing on VOLUME and TIME.. you can set up this problem like this... (v1/t1) x (v2/t2). first we plug in what we know. the first container was filled in 4 minutes so this is our "T1". However we weren't giving the volume of the first container but we were given its dimensions. the volume formula is LxWxH. so we plug in 9x11x12 to get 1188. this is our "V1". the same concept applies for the volume of the aquarium. we have its dimensions so just plug in. 24x25x33 = 19800 this is our "V2". the thing we are left trying to find is T2. so now you can do some cross multiplying and division. (T1xV2)/V1 or (4x19800)/1188 and you get 66.67min or 1h and 6.67mins. and thats how long it took to fill the aquarium.
