James drives her car at 20 kph for 40 km and 40 kph for the next 60 km. What is her average speed for the entire trip?
(20+40)/2=30 kph
A car travels 1 mile at 45 miles per hour What must its average speed be for the next mile in order to average 60 miles per hour for the 2 miles?
The answer is 75 mph. If one travels at 45 mph for one mile, then in order to travel an average of 60 mph for the 2 miles, the rate must be 75 mph (60-45=15). Then add 15 to 60 to get the rate for the second mile. To check the answer add 75 and 45 and divide by 60 (the minutes in one hour) to get the distance (2 miles).
What is a non-example of average speed?
Average speed is not measuring the distance traveled in total, as that is total distance. For example, if a car travels 30 miles in 1 hour and 90 miles in the next 2 hours, the average speed is not calculated as (30 + 90) / 3 hours.
How many hours per mile does a 737 airplane fly?
Since its introduction in 1968, the Boeing 737 has been produced in nine variants. All of them have the same minimum reciprocal speed: 0.001838 hours per mile. All of the variants from the 737-100 to the 737-500 have the same cruising reciprocal speed: 0.002062 hours per mile. The 737 Next Generation variants ... the -600, -700, -800, and -900 ... have a lower reciprocal cruising speed: 0.001957 hours per mile.
If you drive 30 in 40 minutes and then 15 miles in 20 minutes do you have a constant speed?
The average speed over the first 30 miles is equal to the average speed over the next 15 miles. You cannot guarantee that the speed was constant inbetween, though. The average speeds are 45 MPH for each leg.

You are on the ground in Denver (the mile high city) :)
Because the speed of an object can change from one instant to the next dividing the total distance covered by the time of travel given?
Average speed = distance/time
Because of the speed of an object can change from one instant to the next dividing the total distance covered by the time of travel gives what?
Dividing the total distance covered by the time of travel gives the average speed of the object. This average speed represents the overall rate at which the object has covered the distance, taking into account any variations in speed that occurred during the journey.

Bette drives at 60 miles per hour for 2 and a half hours and at 75 miles per hour for 1 and a half hours what is her average rate of speed?
Average speed = (total distance covered) divided by (time to cover the distance)Distance in the first 2.5 hours = (2.5 x 60) = 150 milesDistance in the next 1.5 hours = (1.5 x 75) = 112.5 milesTotal distance = (150 + 112.5) = 262.5 milesTotal time = (2.5 + 1.5) = 4 hoursAverage speed = (262.5/4) = 65.625 miles per hour
