Given:
Jan and Julie started their ride at 09:30 and finished at 15:15.
Stopped for a drink = 20 minutes
Lunch = 45 minute
Rest = 10 minutes
To find:
Time they are riding on their bikes (excluding stops).
Solution:
Jan and Julie started their ride at 09:30 and finished at 15:15.
So, total time of ride including stops is 5 hours 45 minutes or we can say 345 minutes calculated as
[tex]30+60+60+60+60+60+15=345\text{ minutes}[/tex]
We need subtract Drink, lunch and rest time from the total time to get the Time they are riding on their bikes (excluding stops) is
[tex]345-20-45-10=270 \text{ minutes}[/tex]
Therefore, the total time they are riding on their bikes (excluding stops) is 270 minutes.
