Question: What was the total distance traveled?
:
Let d = distance one way:
:
Write a time equation; Time = dist/speed
;
Time at 40mph + time at 45 mph = 4 hrs
: + = 4
:
Multiply equation by; 40*45 = 1800; gets rid of the denominators:
1800* + 1800* = 1800(4)
:
45d + 40d = 7200
:
85d = 7200
d =
d = 84.7 miles, one way distance
:
2*84.7 = 169.4 total miles
:
:
Check our solution: + =
2.1175 + 1.88 = 3.997 ~ 4 hrs
