A train travels (40) km in the first hour and (5) km more each next hour. What is the total distance in (5) hours?

Answer and explanation

Correct answer: 250 km

The distances travelled each hour form an AP: 40, 45, 50, 55, 60. Therefore, \(S_5=40+45+50+55+60=250\) km. 260 km would result from using an incorrect hourly distance or number of terms. In exams, list the first five terms before adding them to avoid mistakes.
