Answer:26.7 and 7.4
Step-by-step explanation:
So, first you add all the time up then the area travelled.
Firstly; 45 mins + 300 minutes(5 hours) + 165 minutes(2.75 minutes)= 510 minutes
Secondly; 42.2KM + 180.5KM + 3.86KM= 226.56KM
Finally: For hourly you would do: 510 divided by 60 to get 510 mins in terms of hours: so, 8.5 hours then you would do 226.56KM divided by 8.5 hours to get: 26.7Km/hr
For m/s: 7.4m/s
