A car went 52 km in the First hour, 60 km in the second hour and 54 km in the third hour. In the fourth hour, there was some trouble in the car, so it could run only 26 km. Its average speed is Options: A . &nbsp46 km. per hr. B . &nbsp48 km. per hr. C . &nbsp56 km. per hr. D . &nbspnone of these

Answer: Option B To find the average speed of the car, we can use the formula: Average speed = Total distance / Total time Here, the total distance covered by the car is the sum of the distances covered in the four hours: Total distance = 52 + 60 + 54 + 26 = 192 km The total time taken by the car is four hours, since each distance is given for one hour: Total time = 1 + 1 + 1 + 1 = 4 hours Using the formula, we get: Average speed = 192 km / 4 hours = 48 km/hour Therefore, the correct option is B. 48 km/hour. Some relevant definitions and formulas to note: Speed is defined as the distance covered by an object in a given time. It is usually measured in kilometers per hour (km/h) or meters per second (m/s). Average speed is the total distance covered by an object divided by the total time taken to cover that distance. Distance is the total length of the path traveled by an object. Time is the duration for which an object has been in motion. The formula for average speed is Average speed = Total distance / Total time. In this problem, we were given the distances covered by the car in each hour and asked to find the average speed. We added up the distances to get the total distance and added up the times to get the total time. Then we used the formula for average speed to get the answer.

Question

A car went 52 km in the First hour, 60 km in the second hour and 54 km in the third hour. In the fourth hour, there was some trouble in the car, so it could run only 26 km. Its average speed is

Options:

A . 46 km. per hr.

B . 48 km. per hr.

C . 56 km. per hr.

D . none of these

Answer: Option B
To find the average speed of the car, we can use the formula:
Average speed = Total distance / Total time
Here, the total distance covered by the car is the sum of the distances covered in the four hours:
Total distance = 52 + 60 + 54 + 26 = 192 km
The total time taken by the car is four hours, since each distance is given for one hour:
Total time = 1 + 1 + 1 + 1 = 4 hours
Using the formula, we get:
Average speed = 192 km / 4 hours = 48 km/hour
Therefore, the correct option is B. 48 km/hour.
Some relevant definitions and formulas to note:

Speed is defined as the distance covered by an object in a given time. It is usually measured in kilometers per hour (km/h) or meters per second (m/s).
Average speed is the total distance covered by an object divided by the total time taken to cover that distance.
Distance is the total length of the path traveled by an object.
Time is the duration for which an object has been in motion.
The formula for average speed is Average speed = Total distance / Total time.

In this problem, we were given the distances covered by the car in each hour and asked to find the average speed. We added up the distances to get the total distance and added up the times to get the total time. Then we used the formula for average speed to get the answer.
