# Buses

Buses Ikarus and Karosa simultaneously started at 8:00 from the final station. Ikarus is returned to the station after 30 minutes. Karosa after 45 minutes. At what time both buses again returned to the station?

Result

x = 9:30 #### Solution:

$30 = 2 \cdot 3 \cdot 5 \ \\ 45 = 3 \cdot 3 \cdot 5 \ \\ \ \\ \text{LCM}(30, 45) = 90 \ \\ x = 8 + 90/60 = 8 + 1.5 = 9:30$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
