The truck can cover 145 miles in 2.5 hours, so the speed of the truck is 145÷2.5=58 miles per hour the car's speed is 1.5 times faster: 58×1.5=87 miles per hour suppose in x hours they will meet: distance covered by truck in x hour: 58x distance covered by car in x hour: 87x total distance: 145 miles 58x+87x=145 x=1
