Question

If t varies as v, and t = 2 and 4/7 when v = 13/14 , find v when t = 2 and 1/4.

Answer 1

((13/14) / (2+(4/7))) * (2+(1/4))
= ((13/14) / ((14/7)+(4/7))) * ((8/4)+(1/4))
= ((13/14) / ((14+4)/7)) * ((8+1)/4)
= ((13/14) / (18/7)) * (9/4)
= (13/14) * (7/18) * (9/4)
= (13*7*9) / (14*18*4)
= 819 / 1008
= 13 / 16
= 0.8125
