Answer:
First Train = 66miles/hour
Second Train=87miles/hour
Explanation:
According to the Question,
- Given That, Two trains leave Towns 612 miles apart at the same time and travel towards each other. one train travels 21 miles/hour faster than the other. When To train Runs Towards Each Other Then The Speed Of train is Added.
Let, Speed of The First Train be X .
So, The Speed of the Second Train will be X+21 .
- Now, If they Meet in 4 hours. We Know, Speed x Time = Distance, On applying this formula we get
612/4 = X + (X+21)
153 = 2x+21
2x = 132
x=66 Now, Put This Value,We get
Speed of The First Train be X=66miles/hour .
And, The Speed of the Second Train will be X+21 ⇔ 66+21 = 87miles/hour.
