a car travelled 60 km in 25 mins. its speed is equilent to _____km/hour. In 2 1/3 hours this car travelled______km if it maintained at this speed.
when you change mins to hour to you divide 60 into 25 to get the km/hour??? im confused.
60km/25 min. = 12km/5min
5 min. is 1/12 of an hour, so multiplying both numerator and denominator by 12 will give you the speed/hour.
Multiply the hourly speed by 2 1/3 to get the distance traveled.
I hope this helps. Thanks for asking.
To convert the car's speed from km/minute to km/hour, you need to multiply the speed by the conversion factor.
Conversion Factor: 60 minutes = 1 hour
Since the car traveled 12 km in 5 minutes, we can calculate the speed in km/hour as follows:
Speed = (12 km / 5 min) * (60 min / 1 hour)
= (12 km * 60 min) / (5 min * 1 hour)
= 720 km / 5 hour
= 144 km/hour
Therefore, the car's speed is equivalent to 144 km/hour.
To find out how far the car traveled in 2 1/3 hours, you can use the speed of 144 km/hour and multiply it by the time:
Distance = Speed * Time
= 144 km/hour * 2 1/3 hours
To multiply a whole number by a fraction, convert the whole number to a fraction and then multiply:
2 1/3 = (2 * 3 + 1) / 3 = 7/3
Distance = 144 km/hour * 7/3 hour
= (144 * 7) km/3
Now, you can calculate the distance traveled by the car in 2 1/3 hours.
