Given:
Deporting time of Bus A and Bus B = 5 pm Β
Time taken by bus A to complete its route = 30 min Β
and , time taken by bus B to complete its route = 35 min
To find :
Time at which both bus back at the bus depot together .
Solution:
The HCF of the times taken to complete their routes will give the time at which they will be together . Β
HCF of 30 and 35 is 210 . Β
The buses will come together after 210 minutes of their deporting time . Β
210 minutes = 3 hours and 30 minutes
The time at which both bus back at the bus depot together Β
= Β ( 5:00 + 3:30 ) Β
= 8:30 pm
