Ответ:
It's C
Step-by-step explanation:
The explanation is in the question itself.
Ответ:
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
