45 minutes.
Don't believe me? Here's the math:
60(miles)=60(minutes)
(minutes)/60=45/60<----miles
multiply both sides by 60
(minutes)=45
there you go
Dividing distance travelled by speed gives 60/40 = 1.5 hours or 1 hour 30 minutes.
60 × 2 = 120 miles
60 miles / 4 hours = 15 miles per hour.
1.07 seconds at 64mph
40 minutes is the time taken to travel 30 miles (48.3 kilometres) at an average speed of 45 miles per hour.
That depends on the speed. Once you decide at what speed you will travel, divide the distance (in miles) by the speed (in miles per hours). The result will be in hours.That depends on the speed.

260 + 90 miles takes 5 + 2 hours ie 330 m in 7 hr, so average speed is 330/7 ie Forty-seven and one-seventh mph
Assuming that the fly is in the car, then yes, it would also be travelling at sixty miles per hour. This is because when the car travels sixty mph, inside, the back of the car pushes the air inside to travel at the same approximate speed. The air then pushes the fly to travel at sixty miles per hour. If the front and back of the car were open (windshield and back window), then the air inside the car would not be moving, although since you would be travelling at sixty miles per hour, it would seem that the air is moving back.
The rate of crossing depends on the speed the boat is traveling, not on the distance it has to travel. 25 miles could probably be crossed in approximately forty-five minutes or less.
Your average speed for the whole trip would be 30 mph.
The average speed is determined only by the total distance traveled and the total time. Thus, the average speed is: (1+10+60) / 6 = 11.83 mph
40 miles is a distance, not a speed, therefore, it can't be measured in terms of velocity.
