The distance between two cities is 145 miles. a truck can cover this distance in 2.5 hours. the speed of a car is 1.5 times faster than the speed of the truck. how long does it take them to meet, if they start moving towards each other simultaneously?

The speed at which the distance is covered by the two vehicles is the sum of their speeds:

... (truck speed) + 1.5×(truck speed) = 2.5×(truck speed)

The time required to cover the distance is inversely proportional to speed, so is

... (2.5 hours)/2.5 = 1.0 hours

It takes 1.0 hours for the vehicles to meet.

The speed of the truck is (145 mi)/(2.5 h) = 58 mi/h

The speed of the car is 1.5 × 58 mi/h = 87 mi/h.

The speed at which they move toward each other is

... 58 mi/h + 87 mi/h = 145 mi/h

So, the time it takes to cover 145 miles is

... (145 mi)/(145 mi/h) = 1.0 h
