A boat can travel a 50km long river upstream (agaisnt the current) in 10 hours. The same boat can travel the same river downstream (with the current) in 4 hours. What is the speed of the boat in still water?
Did you guys have something like that? Or harder pa?
Anyway, good luck with all your quizzes and at least you guys will only have 1 Math subject next year.
uh...our exercises are like that...the quiz was nastier. or maybe that's as hard as the quiz...but i think i got a mental black during the quiz regarding currents (like the one above).
we also have problems regarding just determining time, distance and speed.
quiz ulit kami bukas...same topic. but it's not a retest raw. another quiz toh.

What about clock problems? Meron kayo nun?
The time is now 3:00. At what time right after this time, will the hands of the clock be exactly 20 degrees away from each other?
