100 : 80 = 1,25 ( часа ) 
1,5 часа - 0,5 час = 1 час 
1,25 часа > 1 час 
ОТВЕТ таксисту нужно увеличить скорость

Answer 2

Analysis and Solution

To determine whether the taxi driver needs to increase their speed to arrive at the airport half an hour before the end of passenger registration, we need to calculate the time it will take for the taxi to reach the airport at its current speed and compare it to the remaining time until the end of registration.

Given: - Speed of the taxi: 80 km/h - Distance to the airport: 100 km - Remaining time until the end of passenger registration: 1.5 hours

To calculate the time it will take for the taxi to reach the airport at its current speed, we can use the formula:

Time = Distance / Speed

Substituting the given values:

Time = 100 km / 80 km/h

Calculating the time:

Time = 1.25 hours

Comparing the calculated time (1.25 hours) to the remaining time until the end of passenger registration (1.5 hours), we can see that the taxi will arrive at the airport before the end of registration without needing to increase its speed.

Therefore, the taxi driver does not need to increase their speed to arrive half an hour before the end of passenger registration.
