Tristan is stacking building blocks to make a tower. He takes a break when the tower is 5 2/5 feet tall, which is 1/3 of the height of the tower he wants to build. How tall is the tower when finished? Check all that apply A. 1/3 x ? = 5 2/5

B. 1/3 ÷ 5 2/5 = ?

C. 5 2/5 x ? = 1/3

D. 5 2/5 x 1/3 = ?

E. 5 2/5 x 3/1 = ?

F. 5 2/5 ÷ 1/3= ?

Honestly, I'm not sure how to answer this, but I think this can help you.

Well if 5 and 2 fifths is one third of the total height of the building, then that means to find the total height of the building you need to times 5 2/5 by 3.

(I think F is an answer)

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
