So to find the average speed never use the formula of the averages but try to find the total distance covered and the total time taken. Average speed is measured in units of distance per time and the average speed formula looks like this. So seconds cancel out and were left with kilometers per hour.
So this is equal to 374 kilometers per hour.
A car travels at a speed of 40 kmhr for 2 hours and then decides to slow down to 30 kmhr for the next 2 hours. The expression of the formula for average speed takes place as follows. Dt short form for the change in time Dt t 1 t 2 t 3 t n. If a cars average speed is 65 miles per hour this means that the cars position will change on the average by 65 miles each hour.
