In a trolley ride around an amusement park, a child traveled from one signpost to a second signpost at a constant speed of 125 meters per minute. was the distance that the child traveled from the first signpost to the second signpost greater than 0.8 kilometer? (1 kilometer = 1,000 meters) (1) it took less than 450 seconds for the child to travel from the first signpost to the second signpost. (2) it took more than 400 seconds for the child to travel from the first signpost to the second signpost.

Given speed of trolley = 125 meters per minute

Now we know that

Distance= Speed x time

Thus for the first case since the time of travel is less than 450 seconds thus the distance traveled is less than

Distance < 2.083 x 450 =937.5 meters

hence depending on the given information we cannot come to any conclusion weather the distance travelled is less than 800 m or greater than 800 m.

For the second case

since the time of travel is greater than 400 seconds

Thus the distance traveled is

which is greater than 800 meters.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
