A train left a station at 8:00 am going at 45 mph. A second train left the station at 10:00 am going in the same direction at 55 mph. At what time will the second train catch up with the first train?

At 5:00 pm the second train catch up with the first train.

Step-by-step explanation:

Let t = Time taken by first train.

Time taken by second train = t-2

Speed of train 1 = 45 mph

Speed of train 2 = 55 mph

Since, Distance = speed x time

Then,

After 11 hours, time = 8+11 =17(12+5)i.e. 5 : 00 pm.

Hence, At 5:00 pm the second train catch up with the first train.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
