The jogging track at francine’s school is 3/4 mile long. yesterday francine completed two laps on the track. if she ran 1/3 of the distance and walked the remainder of the way, how far did she walk?

1 mile

Step-by-step explanation:

Given: The jogging track at Francine’s school is long. Yesterday Francine completed two laps on the track. If she ran of the distance and walked the remainder of the way.

To Find: how far did she walk

Solution:

Length of jogging track at Francine’s school

Let the distance covered by running be

Let the distance covered by walking be

Total number of laps completed by Francine

Total distance covered by Francine  

Now,

distance covered by running

distance covered by walking  

Hence, Francine walked for

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
