If walking one way @ 3 Miles Per Hour and jogging back @ 5 miles per hour.
How many miles is traveled in 1 Hour?
:
let d = dist one way
:
Write a time equation; time = dist/speed:
:
+ = 1
multiply by 15, results
5d + 3d = 15
d =
d = 1.875 mi one way
total dist: 2(1.875) = 3.75 mi traveled in 1 hr
;
:
Check by finding the total time:
1.875/3 = .625
1.875/5 = .325
----------------
total time: 1 hr
:
Response to Student comment,"I don't understand why the 1.875 is the distance one way only..please help explain"
I defined d as the distance one way, so the total distance would be 2d which took a total of 1 hr:
The equation:
time out + time return = 1 hr
+ = 1
:
Did this explain it sufficiently? Carl
