Start = 1030
speed = 80 km/h
distance = 620 km

time = 620 /80
time = 7.75 hours
time = 7 hours 45 minutes

time reach at Ipoh
= 1030 + 7 hours 45 minutes
= 1815

Leaves at = 1030
The distance between the 2 cities = 620km
Average speed = 80km/h
______________________________________

Time = distance "divided by" average speed

Time =  \frac{620}{80}
    
        = 7.75 hours
        = 7 hours and 45 minutes

Arrived time,
= 1030 + 7 hours 45 minutes
= 1815
