Solution 1
The answer can be found by using the formula for
Solution 2
The answer can be found by using the formula for time, which is distance divided by speed.
-
First, we need to find the distance the car covers when it's serviced. We know that the car runs at 60 kmph for 6 hours, so the distance covered is 60 km/h * 6 h = 360 km.
-
Now, we need to find out how long it takes the car to cover the same distance when it's not serviced. We know that the car runs at 50 kmph when not serviced. So, the time it takes to cover 360 km is 360 km / 50 km/h = 7.2 hours.
-
To convert 0.2 hours into minutes, we multiply by 60 (since there are 60 minutes in an hour). So, 0.2 hours * 60 minutes/hour = 12 minutes.
Therefore, the car will take 7 hours and 12 minutes to cover the same distance when not serviced. So, the correct answer is 7 hours 12 minutes.
Solution 3
The answer can be found by using the formula for time, which is distance divided by speed.
-
First, we need to find the distance the car covers when it's serviced. We know that the car runs at 60 kmph for 6 hours, so the distance covered is 60 kmph * 6 hours = 360 km.
-
Next, we need to find out how long it takes the car to cover the same distance when it's not serviced. We know that the car runs at 50 kmph when not serviced, so the time taken is 360 km / 50 kmph = 7.2 hours.
-
To convert 0.2 hours into minutes, we multiply by 60 (since there are 60 minutes in an hour). So, 0.2 hours * 60 minutes/hour = 12 minutes.
Therefore, the car will take 7 hours and 12 minutes to cover the same distance when not serviced. So, the correct answer is "7 hours 12 minutes".
