To calculate : Distance travelled by a hybrid car on

Answer to Problem 42PPS
36 miles of distance is travelled by a hybrid car.
Explanation of Solution
Given information : Distance travelled by a hybrid car =
Distance travelled by non hybrid car in 1 gallon = 33 miles
Formula used: 1. Distance travelled by hybrid car (Dh)=
Calculation : According to given question, we first need to calculate the distance travelled by a hybrid car in 1 gallon
Let, Dh= Distance travelled by a hybrid car
And Dn= Distance travelled by a non hybrid car
By using formula 1,
Dh=
Dn= 33 miles (given in question)
By putting the value of Dn
Dh=
=
Thus, distance travelled by a hybrid car in 1 gallon= 45 miles
Now,
Distance travelled in 1 gallon = 45 miles
By putting values in formula 2
Distance travelled in
