Rate-compares 2 quantities measured in different units.
Determine the unit rate in each situation:
a.) An okra swims 110 km in 2 h.
b.) A Canada goose flies 800 km in 12.5 h.
c.) Cathy plants 45 daffodils in 30 min.

1.5 km (1500m)in 75yrs divide by 75
20m/year
Peto
1320 m in 70yrs (1923 - 1993 equal 70) divide by 70
19m/year
