A car travels 60 km in the first 2 hours and 68 km in the next 2 hours. What is the car and acirc and 128 and 153s average speed?

The average speed for the first part of the journey is 30 km/h (60 km / 2 hours) and for the second part is 34 km/h (68 km / 2 hours). The overall average speed for the whole journey is the total distance (128 km) divided by the total time (4 hours), which is 32 km/h.


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.


If the reina family drove 348 miles on the first day of their vacation in 6 hours at that rate how far will they travel in the next 9 hours?

The most important formula to memorize is: Distance = Rate (speed) x Time (hours or minutes, etc..) Therefore, the average rate on the first date can be calculated as follows: Rate = Distance / Speed 348 miles divided by 6 hours = 58 miles per hour. At that rate, a total of 58 miles times 9 hour = 522 miles can be driven by the family in the next 9 hours.


A car travels 30 km at uniform speed of 40km per hour and the next 30 km at a uniform speed of 20 km per hourfind its average speed?

First 30k takes 45 min, second 30k takes 90 min, total 60k in 2¼ hours so average speed = 60 x 4/9 = 26 and 2/3 kph


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


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.


A cyclist rides 30 km at an average speed of 9kmhr At what rate must the cyclist cover the next 10 km in order to bring the overall average speed up to 10kmhr?

In all he will cover 40 km. To do so at an average speed of 10 kph means his total journey will take 4 hours. He has taken 3hr 20 min for the first part (30km @ 9kph), so he has 40 min to cover the final 10km. Required speed is therefore 10 x 60/40 ie 15 kph.


What is speed per hour if you travel 288900 kilometers in 2 minutes 29 seconds?

To calculate speed, you first convert the time to hours: 2 minutes 29 seconds is 2.4833 minutes, or approximately 0.0414 hours. Next, divide the distance traveled (288900 km) by the time taken (0.0414 hours) to find the speed. The speed would be approximately 6,970,531 km/h.
