Average speed of Tomas for his walk home from school was 1.2 km/hr.
Total Distance from school to home = 2 km
time at which he left Killough = 4:28 pm
time he reached home = 6:48 pm
Time interval he played X box at Joshua's house =40 mins.
We need to find the total average speed for his walk home from school.
Time Spent on Journey
4:28 pm + 6:48 pm = 2 hours and 20 mins.
Time played X box at Joshua's house = 40 minutes.
So we will reduce the time played X box at Joshua's house from the time spent on Journey.
2 hours and 20 mins - 40 mins = 1 hour and 40 mins.
40 mins =
1 hours and 40 mins =
Hence Total Time spent on journey = 1.67 hrs.
Distance traveled = 2 Km
Now we know that Average Speed is equal to Total Distance divided by Total time taken to travel the distance.
framing in equation form we get;
Average speed =
Hence Average speed of Tomas for his walk home from school was 1.2 km/hr.
