What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
SANDRA BIKED 800 METERS ON FRIDAY.
ON SATURDAY, SHE BIKED 3 KILOMETERS.
ON SUNDAY, SHE BIKED 2 KILOMETERS, 500 METERS.
So, 800m = 0.8km
500m = 0.5km
The total kilometer
= 3 km + 2.5 km + 0.8 km
= 6.3 km
Hence, Sandra traveled 6.3 km with her bike over the three days.
