The distance between the two villages is 150 km. To get from one village to another, the traveler walked for 3 hours at a speed of 5 km / h, after which he drove the remaining distance in a passing car. How much distance did he drive in a passing car?
Suppose the traveler drove x km in a passing car, walked 5 km / h * 3 hours. The total distance was 150 km. Then we can write the equation:
x + 5 * 3 = 150
x + 15 = 150
x = 150-15
x = 135
For x, we took the distance traveled by the traveler by car.
Answer: the traveler drove 135 km by car.
