Ludmilka [50]

Answer:

The wall is 90 meters wide.

Step-by-step explanation:

1cm=6cm

15m=wm

2. cancel out the like units on both sides of the equation

1=6

15=w

3. Equate the cross products, and then solve for w:

1*w=15*6

w=90                                                                                                                                          The actual width of the wall is 90 meters.

Minchanka [31]

1. If Martin climbs 3 1/3 meters in the first one 1/6 hour, then he climbs

2. If Alexia climbs 17 1/2 in the first 5/6 hour, then she climbs

17\dfrac{1}{2}\cdot \dfrac{6}{5}=\dfrac{35}{2}\cdot \dfrac{6}{5}=21 meters per hour and it takes Alexia \dfrac{1}{21} of an hour to climb 1 meter. Then options B and D are correct and option F is false.
