science =
English =
Math = 4 hours
Step-by-step explanation:
let the number of hours spend on science = x
Hence the number of hours on English will be = 2x
Given that the number of hours spend on science is one third of the time spend on maths. Hence the time spend on math is 3 times that of the time spend on science. That the time spend on maths is = 3x
Hence the total time to study is
x+2x+3x
which is given as 8 hours
Hence
x+2x+3x =8
6x=8
dividing both sides by 6
Hence the number of hours foe studying science =
Number of hours to study English = =
Number of hours to study Math= =
