Answer:
Step-by-step explanation:
Alright, lets get started.
For train A:
Distance from Milford and Pinkerton is 300miles.
Speed of train A is 90 miles per hour.
So, time taken to complete this distance =
So, time taken to complete this distance =
Means train A will take 3.33 hours or say 3 hrs and 19.8 minutes to reach Pinkerton.
So,if it starts at 10:00 AM, then it will reach at 01 hrs 19.8 minutes PM (01:19.8 PM).
For train B:
Speed of train B is 70 miles per hour.
Train B will take time =
Means 4 hrs and 17.4 minutes.
So, if it starts at 8:00 Am, then it will reach at 12 hrs 17.4 minutes PM(12:17.4 PM).
So, train B will be reaching Pinkerton before 1:00 PM : Answer

According to the Pythagorean theorem:
a² + b² = c²
a = 4
b = 1
c = ?
4² + 1² = c²
c² = 16 + 1
c² = 17
c = √17
