Solution:
Two trains are moving in opposite direction with Speed 40 kmph and 60 kmph. Make train B stationary and then take the Speed of train A relative to the train B. So relative Speed of train A = 40 + 60 = 100 kmph. Before it crashes into the stationary train B it has to travel a Distance of 200 m which it will do in (0.2/100 ) hours. During this duration, the average Speed of bird has been 10 kmph i.e. before the crash total Distance covered by the bird = 0.2 * 10/100 km = 20 meters.

Add 16+12 to get 28.
Add 9+12 to get 21.
Think of these as the sides of a triangle.
a^2+b^2=c^2
28^2+21^2=1225
√1225=35
You threw the ball 35 feet.
Answer:
3 and 6
Step-by-step explanation:
3*6=18
18+3=21
The common ratio of a geometric sequence is the ratio of any term to the one before it. Here, you can find it by
... 6/-2 = -3
or, if you prefer the minus sign in the numerator, ...
... -18/6 = -3
or the ratio of any other sequential terms.
The common ratio is -3.
