Mr. Walker was hiking across Massachusetts. He has three days to cover 70 miles. On the first day, he walked 6 hours at a speed of 4 mph. On the second day he walked the same number of hours, but his speed was only 3 mph. On the third day, he walked 8 hours to cover the remaining distance. What was his speed on the third day?

3.5 is the correct answer it was complicatited

So 6 hours at 4 miles per hour

4 miles per hour means 4 mieles in one hour

6 hours

distance=time times (distance pers unit of time)

distance=6 times 4=24

second day

same number of hours=6

speed=3

distance=time times (distance per units of time)

distance=6 times 3=18

so we add 1 and 2 days together

24+18=42

so he has covered 42 mles

he eed to cover 70

70=42+rest

subtract 42

28=rest

so he traveled 28 miles on third day

in 8 hours

sppeed=distance divided by time

time=8

distance=28

28/8=14/4=7/2=3 and 1/2 miles per hour=3.5 miles per hour

answer is 3.5 miles per hour
