B Correct answer
Explanation

Distance = speed * time. 40 km/h * 0.25 h = 10 km. 60 km/h * 0.25 h = 15 km. Total = 10 + 15 = 25 km.

AI explanation

Using the formula distance equals speed multiplied by time, the first distance is 40 km/h multiplied by 0.25 hours, yielding 10 km. The second distance is 60 km/h multiplied by 0.25 hours, yielding 15 km. The total distance covered is 10 km plus 15 km, resulting in 25 km.
