Sagot :
Solution: 30 minutes
Step by step solution:
First I found how many minutes it took Jan to do the same amount of work (2x45=90 mins) then I write that in an equation: x/90+x/45=1 (x being the amount of work each of them did), from there on it’s just algebra
x/90+x/45=1
x/90+2x/90=1
3x/90=1
x90 x90
3x=90
/3 /3
x=30
30 mins
