Answer 2

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 =
`(distance)/(speed)`

So, time taken to complete this distance =
`(300)/(90)=3.333`

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 =
`(300)/(70)=4.29`

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

Hope it will help :)
