Your family has planned a trip this summer. The distance from your home to Havertown is 38 miles. Then, your family must travel 948 miles to Murrayville. Use front-end estimation to determine how many miles you will travel on your family trip. Student Answer: 960 970 980 990

jimthompson5910 (jim_thompson5910):

38 miles is close to 40 948 is close to 950 Add these two estimates: 40+950 = 990

jimthompson5910 (jim_thompson5910):

So the estimated total distance is 990. This is an overestimate (since both 40 and 950 are found by rounding up)
