Answer:
Flight arrived in london on 5 : 35 pm Wednesday
Step-by-step explanation:
Time = 16 h 35 min
Time difference = 7 h
Flight time = 8am
So
According to perth time flight reached in london is
8 am + 16 h 35 m = 8 am + ( 12 h + 4h + 35 m) =
8pm + 4h +35 = 12am + 35m = 12 : 35 am
The time difference is 7 h ,so minus this from perth time
12 : 35 am - 7h = 5 : 35 pm

Riding time after lunch = 41.
Riding time before lunch = 5 * 41 - 1
5 * 41 - 1 =
= 205 - 1 =
= 204
It means Javier rode his bike for 204 minutes (3 hours and 24 minutes) before lunch.
