There are three basic equations for distance=+D, speed+=S, and time+=T.
Actually, they are the same equation rewritten to calculate each specific element. In each case when two elements are known, they are used to find the third which is unknown. The equations are:
D+=+S+%2A+T%2F60+
S+=+60D%2FT+
T+=+60D%2FS+
If average speed of S=66ml%2Fh and the time T is 3 hours and 40 mintues, then:
S=66ml%2Fh
T+=+3h_and_40_min……….we need 40+_min in hours which is 40%2F60=.66,
So T+=+3.66h
D+=+S+%2A+T%2F60+
D+=+66ml%2Fh%2A+3.66h+………cancel h
D+=+241.56ml
