The speeds at the intervals are
1) 5km/day
2) 2km/day
3)2km/day
4) 6km/day
5) The turtle starts with speed of 5km/day from 0 to day 2. It slows to 2km/day and continue at constant speed between day 3 and day 4. It then increases its speed between day 4 and day 6 to 6km/day.
How to determine the speed of the turtle
From the provided graph
Speed = distance covered/Time
The distance is in km and time in days, therefore speed will be expressed in km per day.
1) Between 0 and 2 days
Distance = 10km
Time = 2 days
Speed = 10/2
= 5km/day
2) Between 2days and 3days
Distance = 12-10
= 2km
Time = 1 day
Speed = 2/1
= 2km/day
3) Day 3 to day 4
The speed is constant
No Change in speed
Speed remains 2km/day
4) Day 4 to Day 6
Distance = 24 -12
= 12km
Time = 6-4 = 2 days
Speed = 12/2
= 6km/day
The turtle starts with speed of 5km/day from 0 to day 2. It slows to 2km/day and continue at constant speed between day 3 and day 4. It then increases its speed between day 4 and day 6 to 6km/day.
