A car travels 27.4km in 20 min
find its speed in km per hour.
Speed= Distance divided by time
= 27.4km divided by 20 minutes
= 1.37km/h
It must be 137km/h
To find the speed of the car in km per hour, you need to convert the time from minutes to hours.
Given:
Distance traveled = 27.4 km
Time taken = 20 min
To convert minutes to hours, divide the time by 60 since there are 60 minutes in an hour.
20 minutes ÷ 60 minutes/hour = 0.3333 hours
Now that you have the converted time in hours, you can find the speed by dividing the distance by the time.
Speed = Distance ÷ Time
Speed = 27.4 km ÷ 0.3333 hours
Calculating this:
Speed = 82.223 km/h (rounded to three decimal places)
Therefore, the speed of the car is approximately 82.223 km/h.
