Question:
A swimmer is able to swim at a speed of 0.90 m/s in still water.
(a) How long does it take the swimmer to go a distance of 1500 m in still water? Call this time t1.
(b) The swimmer then decides to swim the same distance in a river having a current with a speed of 0.50 m/s. How long does this take if she swims with the current? Call this time t2.
(c) How long does it take her to swim the same distance against the current? Call this time t3.
(d) Explain why t1 - t2 is not equal to t3 - t1.

I have worked with very different types of students, from little kids to bussines men and women. I have thaught at universities, schools, but mostly in private sessions for specialized purpuses. Sometimes I tutored kids that needed help with their classes at school, some others were high school or college students that needed to prepare for an exam to study abroud. Currently I'm teaching bussiness English for people in bussiness positions that want to improve their skills, and preparing and ex-student to pass a standarized test to study in the UK.
