To calculate the distance traveled, we need to convert the time from minutes to hours since the speed is given in kilometers per hour.
Given: Speed = 90 km/h Time = 45 minutes
To convert 45 minutes to hours, we divide it by 60 (since there are 60 minutes in an hour):
45 minutes ÷ 60 = 0.75 hours
Now we have the time in hours. To calculate the distance, we use the formula:
Distance = Speed × Time
Plugging in the values:
Distance = 90 km/h × 0.75 hours
Distance = 67.5 kilometers
Therefore, if a car travels at a speed of 90 km/h for a time of 45 minutes, the distance traveled would be 67.5 kilometers.
