<span>speed = distance/time
total time is 8 hours
outgoing speed is 160 km per hour,
so time = d/160
</span><span>returning speed is 240 km per hour,
so time = d/240
d/160 + d/240 = 8
3d/480 + 2d/480 = 8
5d/480 = 8
5d =480 (8)
5d = 3840
d=3840/5
d=768
answer: so the distance is 768 km</span>

Step-by-step explanation:
where the question at
Answer:
The actual dimensions of the closet are 2 ft by 3 ft.
Step-by-step explanation:
According to the scale, 1/4 inch <--> 1 foot
The closet dimensions on the scale are (1/2 inch, 3/4) or (2/4 inch, 3/4). Let the real closet dimensions be (x,y).
In this case, the rule of three can be applied to find the missing term of a proportion:
The actual dimensions of the closet are 2 ft by 3 ft.
It would certainly be a lot easier to answer if we could see all of the numbers
in the question but, sadly, part of the first line is outside the picture.
Square kilometers = (one dimension in km) x (the other dimension in km) .
Then, since each square km = 100 ha,
The number of hectares is (100) x (number of square km) .
