Question 731965: I have tried to work out the average speed of four vehicles.
one travels at 50mph another at 46mph another at20mph and another at 5mph.
the average speed I get is 24.9mph and 30.25mph, but that doesnt seem right to me.
If you are able to show the workings as opposed to just saying I am right/wrong I would appreciate it
