To find the distance traveled by a car, we need to multiply its speed by the time taken. In this case, the car is traveling at a constant speed of 40 mph, and we want to determine the distance traveled in 45 minutes.
First, let's convert the time from minutes to hours. There are 60 minutes in an hour, so 45 minutes is equal to 45/60 = 0.75 hours.
Now we can calculate the distance traveled:
Distance = Speed × Time
Distance = 40 mph × 0.75 hours
Distance = 30 miles
Therefore, the car will travel 30 miles in 45 minutes.
