On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is LaTeX: t=\frac{\:1}{500}dt=1500d How long will it take the airplane to travel 500 miles?

7.2 sec

Speed of plane is 500 mph which is 500/60 mpm

Which is 500/60x60 mps→ 5/36 mps

Now to find the time in traveling 1 mile distance we use the simple formula d=s x t

d= 1 mile

s=5/36 mile per sec

Now t=d/s

=1/(5/36) sec

=36/5 sec

=7.2 sec

I hope it help you,

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
