You can put this solution on YOUR website! Anne and Mary went for a walk. Anne started walking 1 minute earlier than Mary did.
•Anne walks at a speed of 6 feet per second
•Mary walks at a speed of 8 feet per second
How many seconds had Anne been walking at the point when the two girls had walked the exact same distance?
:
let t = walking time of Anne in seconds
then
(t-1) = walking time of Mary
:
Write a distance equation: dist = speed * time
Mary's dist = Anne's dist
8(t-1) = 6t
8t - 8 = 6t
8t - 6t = 8
2t = 8
t = 8/2
t = 4 seconds Anne's walking time
:
:
Check this by finding actual dist each walked, should be equal
4*6 = 24 ft
3*8 = 24 ft
