<u>Solution-</u>
Two cars leave the same location traveling in opposite directions.
The first car leaves at 3 p.m and has a speed of 55 mph
The second car leaves at 4 p.m and has a speed of 75 mph
Let x hours after the first car leaves, the two cars are 380 miles apart from each other.
In this x hours, distance covered by the first car,
As the second car leaves at 4 p.m i.e 1 hour late as compared to the first car, so distance covered by the second car in (x-1) hours,
According to the question,
∴ After 3.5 hours from 3 p.m i.e at 6.5 p.m the cars will have a distance of 380 miles.
