You can't answer that question because you don't know how fast you went. The formula for finding the speed would be v=d/t (derived from the formula d=vt for distance, d being distance, v being velocity [speed] and t being time.) You have to have two variables to find the third, so you would need to know the distance you drove as well.
26.56 mph
Hints: speed = (distance) / (time) You need to convert 1 hour + 45 minutes into a single unit, such as hours or minutes.
It depends on the average speed of the car. That, in turn depends on the car, speed limits (and whether you heed them), road conditions, traffic, your driving style, etc.
542 miles in 12 hours and 37 minutes equates to an average speed of 42.96 miles per hour.
55 minutes is 55/60 hours. 6km divided by 55/60 = 6.5km/h
2 hours 30 minutes, within speed limits
4 hours 10 minutes
If the 1500 meters were run in 3 hours and 32 minutes the average speed would be 0.264 miles per hour.
The average speed is 332.31 miles per hour.
Traveling 117 miles in 2 hours and 15 minutes means the average speed is 52 miles per hour. (Divide 117 by 2.25)
What speed will you be doing? At an average of 50 mph, it is almost 4 hours At an average of 60 mph, it is 3 hours and 20 minutes at an average of 70 mph, it is 2 hours and 50 minutes
14.4 km per hours
46.64788km/h
26.56 mph
That depends on the speed you drive, if your average speed for the whole journey is 30mph then it will take approx 3.5 hours, if your average speed is 50mph then it will take approx 2 hours 7 minutes.
It depends on the speed at which you can drive. That, in turn, depends on your speed limits, your vehicle, road conditions, traffic. Time = Distance/Average Speed
It travels 288 miles in 4 hours 30 minutes at that speed.
