Answer:
270 miles
Step-by-step explanation:
if 1 gallon = 18 miles
then 15 gallons = x miles
cross multiply
1 × x = 15×18miles
x = 270 miles
so it travels 270 miles on 15 gallons of gasoline
Answer:
1800
Step-by-step explanation:
(1/2)/100 of x = 9
1/2*1/100 of x = 9
1/200 of x = 9
x/200 of x = 9
x = 9*200
x = 1800

t how much time will elapse before they are 20 miles apart
(12mph)t + (6mph)t = 180mi
18t = 18
t = 10hrs, the time that will elapse before they are 20 miles apart
