On a recent drive from exeter to nyc, taylor maintained an average speed or 50 mph for the first 4 hrs, but could only average 30 mph for the final hour, because of road construction. what was taylor's average speed for the whole trip? what would be the avg speed taylor traveled h hours at 30 mph and 4h hours at 50 mph? what would be the avg speed if taylor traveled m miles at 30 mph and 4m miles at 50 mph?
+37146 Average speed = total distance / total time
= (50 m/hr *4 hr + 30 m/hr *1 hr) / ( 4+1 hrs)
= 230 miles / 5 hrs = _______________ m/hr
See if you can do the others...........
