The distance between Party A and Party B is 174km. Trucks and buses leave from two places in the same direction at the same time. Trucks travel 60 kilometers per hour and buses travel 63 kilometers per hour. After two-thirds of the time, how many kilometers are the two cars apart? (List all possible situations)

The truck will leave in two-thirds of an hour: 60 times two-thirds = 40 kilometers.

Departure in two-thirds hours: 63 times two-thirds = 42 kilometers.

Buses are faster than trucks: 42-40 = 2 kilometers.

Distance1:174+2 =176 km.

The distance is 2: 174-2 = 172km.
