Answer:
add all together
Step-by-step explanation:
M/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2
m=22.5
<u>Answer:
</u>
In 3 hour 15 minutes Dennis will walk 9.2072 miles.
<u>Solution:
</u>
It is given that Dennis can walk 2.833 miles each hour. We have to find how far will he walk in 3 hours 15 minutes.
