What is the origin of miles per hour?
A unit of distance (miles) traveled in a certain time period (one hour) to calculate speed. Speed=(time/distance).
The formula to calculate your speed if you went 75 miles in 120 minutes?
Speed (in miles/hour) = distance (miles) / time (hours= 75/ (120/60) = 37.5 miles/hour
A man travels a certain distance at 60 miles per hour and returns over the same road at 40 miles per hour What is his average rate for the round trip in miles per hour?
50 miles per hour.
What two measurements must be made to calculate average speed?
If we know the distance something has moved, and the time it took to move there, we can calculate average speed by dividing the distance by the time.If a truck went 60 miles in 2 hours, it averaged 60/2 miles per hour, or 30 miles per hour.
How many minutes would it take to go 42.5 miles at 60 miles per hour?
To calculate the time it takes to travel a certain distance at a given speed, you can use the formula: time = distance / speed. In this case, it would be 42.5 miles / 60 miles per hour = 0.708 hours. Since there are 60 minutes in an hour, you would convert 0.708 hours to minutes by multiplying by 60, resulting in approximately 42.5 minutes.
