Problema Solution
for exercise mae jogs 2 miles then walks an additional 4 miles. if her jogging speed is 4.5 miles per hour faster than her walking speed and her total exercise time is 3 hours what is her walking speed
Answer provided by our tutors
let
v = the walking speed, v>0
v + 4.5 = the jogging speed
d1 = 2 mi the jogging distance
d2 = 4 mi the walking distance
since speed = distance/time follows time = distance/speed
d1/v + d2/(v + 4.5) = 3
2/v + 4/(v + 4.5) = 3
