A car journey is spread over 5 hours. In the first hour the car travels 1/3 of the total distance. In the second hour it travelled 1/3 of the remaining distance. In the third hour the car travelled 1/4 of the remaining distance. In the fourth hour the car travelled 1/2 of the remaining distance. There are 10 miles left to travel. How far has the car travelled?
The correct answer is 50 miles. However, Socratic interpreted this question as:
A car travels 165 miles in 5 hours. How many miles does it average per hour?
Despite the above, the app is excellent when it comes to solving algebra problems.
