can anyone explain to me wat i am doing?
for qn part (b), i got it correct when i did it last year but now when i look back, i dont understand what i am doing.
this is wat i did:
dist travelled by bicycle:2d
dist travelled by bicycle:d
T X 5 = 2d
0.5 X T X T/5 = d (i dont understand this step)
T^2/10 = d
T^2 / 5 = 5T
The above method is correct as my teacher marked it last year already. Now i just need someone to remind me of why i did this. Thanks
