Firstly: 3.3/4=15/4 h
She can walk 15÷(15/4)=4km in one hour
4*0.5=2km
So this woman can walk 2km within half an hour.
Answer:
B = 6√10
Step-by-step explanation:
In the attached file
Perimeter of rectangle:
P = 2(L + W)
P = 250 (given)
L = 3W - 35 (given)
250 = 2(3W -35 + W) ↔ 125 = 4W - 35
4W = 125 +35 =160 And W = 40 ft
And L = 3x40 - 35 = 85 ft
To find the amount of miles/gallon, we have 540 miles/18 gallons=30 miles/gallon. As we add 30 miles for every gallon, the amount of miles traveled is 30*x (e.g. if x is 1 then 0+30=30 and if x is 2 then 30+30 (2 times)=60) with x being the amount of gallons. For b, we just plug 12 in for x to get 20*12=360
It will take the train 14 hours to reach miles,
I got this by dividing 35 by 490.
