A car travels the first 50 km at a uniform speed of 25 kmph and the next 60 km at a uniform speed of 20 kmph. Calculate the average speed of the car in kmph
Question
A car travels the first 50 km at a uniform speed of 25 kmph and the next 60 km at a uniform speed of 20 kmph. Calculate the average speed of the car in kmph
Solution
To calculate the average speed of the car, we need to find the total distance traveled and the total time taken.
Step 1: Calculate the time taken for the first 50 km. Time = Distance / Speed Time = 50 km / 25 kmph Time = 2 hours
Step 2: Calculate the time taken for the next 60 km. Time = Distance / Speed Time = 60 km / 20 kmph Time = 3 hours
Step 3: Calculate the total distance traveled. Total Distance = 50 km + 60 km Total Distance = 110 km
Step 4: Calculate the total time taken. Total Time = 2 hours + 3 hours Total Time = 5 hours
Step 5: Calculate the average speed. Average Speed = Total Distance / Total Time Average Speed = 110 km / 5 hours Average Speed = 22 kmph
Therefore, the average speed of the car is 22 kmph.
