Problema Solution
The amount of gasoline used by a car varies jointly as the distance traveled
and the square root of the speed. Suppose a car used 25 liters on a 100
kilometer trip at 100 km/hr. About how many liters will it use on a 192
kilometer trip at 64 km/hr?
Answer provided by our tutors
G=k*d*(square root of S)
25=k*100*(square root of 100)
25=k*(100 x 10)
k = 25/1000 = 0.025
G=0.025*d*(square root of S)
G=0.025*192*(square root of 64)
G=38.4 liters
