To arrive at its destination on time, a bus should have maintained a speed of V kmh throughout its journey. Instead, after going the first third of the distance at V kmh, the bus increased its speed and went the rest of the distance at (1.2)*V kmh. If, as a result, the bus arrived at its destination X minutes earlier than planned, what was the actual duration of the trip?
1. V = 60
2. X = 20
OA - B
1. V = 60
2. X = 20
OA - B
