recall,and the second one may sound stupid but i couldnt get it
anna drove 35 miles from southhampton to basingstoke
she drove at an average speed of 20 mph for the first 5 miles
and then an average speed of 60 mps for the remaining 30 miles
calculate her average speed for the whole journey.
plz help and if you say how you got would be better thanks!
we know the distance, now we need to find the time. (here, of course, i'm talking about average speed, total distance, and total time)
the time we are looking for will be the sum of the times for the two parts of the journey. so, how much time did she take to drive the first 5 miles? how much time did she take to drive the last 30 miles? Hint: you can use the same formula i gave you above
