D=rt and we are told d=546 and r=1.3m/s so
1.3t=546 divide both sides by 1.3
t=420 seconds so
420s(min/60s)=7 min
So it takes him 7 minutes to walk to Sara's house.

I used googles calculator home that helps
You can conclude that X is smaller than Y. For example:
(2,5)
2 + 5 = 7
2 - 5 = -3
Hope this helped!
h=20w
in one week hector works 20 hours
in two hector works 40 etc
h = hours and w = weeks. the money is just extra information.
h=20w works because if it has been two weeks we substitute the w with the number 2 and can solve
h=20(2)
h=20x2
h=40
This proves that the equation is true
The answer is Lisa, because there can be only one answer to the question
