First question in physics last night in paper one
ayoubi:
it was very very tricky...
i chosed C as the answer of 60km/h by adding 90+30/2
what about you guyz?
bball92:
i chose 50, because even though the top speed of the car was never more than 90 and lowest speed was 30, the total distance travelled was 100KM, if you took 60 as ur average speed per hour for your journey, that would mean u end up travelling 120km overall which is incorrect :S.
Thats the way i looked at it :P
IGis2easy:
no man ure rite its 90 + 30 /2 giving 60 ;D
i am pretty sure cuz i checked the answer with ma teacher ;) :D
susman:
well i thought the max and min speed was given to confuse you...
avg speed is total distance / total time taken..
it comes out to be 50 km/hr
the 60 km/hr is wrong
thukon:
60km/h is WRONG. 50 is correct. They gave you the max and min values to confuse you. Your physics teacher must be like my physics teacher/
