A car covers 30 km at a uniform speed of 60km/h & next 30km at a uniform speed of 10km/h find the total time taken
To find the total time taken, we need to determine the time taken for each part of the journey separately and then add them together.
First, let's calculate the time taken for the car to cover the first 30 km at a speed of 60 km/h.
Time = Distance / Speed
Time = 30 km / 60 km/h
Time = 0.5 hours
Next, let's calculate the time taken for the car to cover the next 30 km at a speed of 10 km/h.
Time = Distance / Speed
Time = 30 km / 10 km/h
Time = 3 hours
Finally, we add the time taken for the first part and the second part together to get the total time taken.
Total Time Taken = 0.5 hours + 3 hours
Total Time Taken = 3.5 hours
Therefore, the car takes a total of 3.5 hours to cover the entire distance.
This is science? What are you doing in math?
time=30/60 hr + 30/10 hr
looks like 3.5 hrs
