Let us say that the variables for flight is designated by
1, while the return flight by 2, since the distance travelled are equal, therefore:
v1 t1 = v2 t2
or
460 t1 = 500 t2
Since t1 + t2 = 4.8, therefore: t1 = 4.8 – t2
460 (4.8 – t2) = 500 t2
2208 – 460 t2 = 500 t2
960 t2 = 2208
t2 = 2.3
t1= 4.8 – t2 = 4.8 – 2.3
t1 = 2.5
Answer:
The flight took 2.5 hours while the return flight took
2.3 hours.
The ratio would be 4:6 because 4 of the marbles are pink and 6 (the rest) are blue
i'd say it would be 4 over 1 4/1 so you go up 4 and to the right 1 if they were negative then it would be the oposite way around.
Answer:
this is the formula u can use it on any Pythagoras theorm problem
Answer:
(2) sqrt( 2d /a) =t
Step-by-step explanation:
d = 1/2 a t^2
Multiply each side by 2
2d = 2*1/2 a t^2
2d = a t^2
Divide each side by a
2d/a = a t^2 / a
2d /a = t^2
Take the square root of each side
sqrt( 2d /a) = sqrt( t^2)
sqrt( 2d /a) =t
