Question 52372
(distance)=(rate)(time) or d=rt
rate to Disnseyland:50
rate from Disneyland:30
time to Disneyland:t
time to Disneyland+time frome Disneyland=7.2 therefore time from Disneyland:7.2-t
Distance to Disneyland=50t
Distance from Disneyland=30(7.2-t)
These two distances are equal, therefore:
50t=30(7.2-t)
50t=216-30t
50t+30t=216-30t+30t
80t=216
80t/80=216/80
t=2.7 hrs
Plug this t into the distance equation going to Disneyland.
Distance to Disneyland=50(2.7)miles
Distance to Disneyland=135 miles
If you check the distance from Disneyland in the same way, you'll get the same answer.
