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?
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
