Final answer:
By using the formula distance = speed × time, and converting 12 minutes to hours (0.2 hours), we calculate that a car travelling at 35 km/h for 12 minutes covers a distance of A) 7 km.
Step-by-step explanation:
The subject of the question is mathematics, specifically involving speed, distance, and time calculations within the realm of physics. To find the distance travelled by a car in a given time at a constant speed, we use the formula: distance = speed × time. The student has asked the question: In 12 minutes a car whose speed is 35 km/h travels a distance of A.7 km B.35 km C.14 km D.28 km. Let's calculate: The speed of the car is 35 km/h, and we need to convert 12 minutes into hours. Since 60 minutes make an hour, 12 minutes is equal to 12/60 hours, which is 0.2 hours. The distance travelled would therefore be 35 km/h × 0.2 h = 7 km. So, the correct answer is A. 7 km.
