A speed boat is travelling from Florida to Cuba (distance of approximately 380 km), it is directly affected by

the water current. Thus, the actual speed of the boat with respect to the ground is the speed of the boat (125
km/h) plus the water current speed, c.
a) Develop an equation of the total time it takes to make a round trip if the current is c. HINT: Distance = velocity x time
Isolate for current with respect to time.
b) Then state the domain & range of this application.
