A 50-ft ladder is placed directly against the side of a large building. The base of the ladder is resting on ice, and it slips away from the building at a rate of 3 ft per minute. How fast is the top of the ladder slipping down the wall at the instant when the base of the ladder is 30 ft from the building?

In 16 Minutes the ladder will hit the ground.

Step-by-step explanation:

50 is at the top of the building.

the base is 30 feet from the building. If the top of the ladder is falling 3 ft every minute in 16 minutes it will hit the ground.

Hope it helps

step-by-step explanation:

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
