A train leaves the station at 9:00 pm traveling east at 36 miles per hour a second train leaves the station at 10:00 pm traveling west at 42 miles per hour at what time will both trains have traveled the same distance

Answers

Answer 1
Answer: Add the time they arrive at the common to individual starting points.
9.00 +(x)/(36) =10.00 + (x)/(42)
put the like terms together;
10.00 - 9.00=(x)/(36) - (x)/(42)
1=(42x-36x)/(36*42)
1=(6x)/(36*42)
6x=36*42
x=(36*42)/(6)
x=252 miles

Answers

The radius of circle a is 5

Let, area of circle a = a   and of b = b

A.T.Q,

36a = b

36a = 30

a = 30/36 = 5/6

πr² = 5/6
