For Monday
To check if the unit rate is constant, we will compare the time to the distance covered
For 20-40 mins:10-5=5km
For 60-40 mins:12-10=2km
For 80-60 mins:14-12=2km
For 100-80 mins: 16-14=2km
We can observe that the time increases at intervals of 20 min while the corresponding time distance varies between 5km and 2km, we can conclude that Monday's table cannot be described by a constant unit rate.
For Tuesday
To check if the unit rate is constant, we will compare the time to the distance covered
For 20-40 mins:8-4=4km
For 60-40 mins:12-8=4km
For 80-60 mins:16-12=4km
For 100-80 mins: 20-16=4km
We can observe that the time increases at intervals of 20 min while the corresponding time distance remains constant at 4km, we can conclude that Tuesday's table is described by a constant unit rate.
