Speed problems: The Speed Table - Handling Speed Problems with Data Overload

Jemma takes 2 hours to swim the 4 miles from buoy _A_ to buoy _B_. Tired from her swim, she then continues to buoy _C_ at half her previous speed. If buoy _C_ is 6 miles away from buoy _B_, how many more hours will pass before Jemma reaches Buoy _C_?

Correct. [[snippet]] This is what the table looks like: | | SPEED (MILES/HR) | TIME (HR) | DISTANCE (MILES) | |-------------------|---------------------|----------------------|--------------| | _A_ $$\rightarrow$$ _B_ | $$\frac{4}{2} = 2$$ | $$2$$ | $$4$$ | | _B_ $$\rightarrow$$ _C_ | $$\frac{1}{2}\times2=1$$ | {color:red}$$?$${/color} | $$6$$ | Therefore, it takes Jemma $$\frac{6}{1} = 6$$ hours to reach Buoy _C_.
