From one bus station along the same route with an interval of 1 hour, a bus first departed, -60 km / h

From one bus station along the same route with an interval of 1 hour, a bus first departed, -60 km / h, and a taxi -80 km / h. After how many hours the taxi will catch up with the bus

Given:
Interval – 1 hour;
Bus speed – 60 km / h;
Taxi speed – 80 km / h;
Through sc. hours aut. will catch up with a taxi =?
Solution:
1) Since the bus departed from the bus station one hour earlier than the taxi, it means by the time the taxi departed, the bus passed:
60 * 1 = 60 (km.)
2) Find how much the taxi speed is faster than the bus speed. Then:
80-60 = 20 (km / h);
This means that for every hour of travel, the distance between the bus and the taxi is reduced by 20 km;
3) To find in how many hours the taxi will catch up with the bus, you need to divide the distance that the bus traveled before the taxi departed by the reduction in the distance between the bus and the taxi for each hour. Then:
60: 20 = 3 (h.)
Answer: 3 hours.
