Answer:
1000 miles
Step-by-step explanation:
Given the following :
Number of miles driven :
First trip = 240 miles
Second day = 205 miles
Third day = 315 miles
Fourth day; miles driven before arriving at their final destination = 220 miles
Total number of miles driven after 4 days before reaching their destination :
(240 + 205 + 315 + 220) = 980 miles
However, they still haven't reached their destination ;
Using front end estimation :
We can take the total miles recorded and make an estimation based on the first digit of the recorded miles traveled:
In other to estimate 980 using front end estimation : the actual number is replaced with a number with only one nonzero digit (which is the first digit)
Hence,
980 - - - - > we round the digit after 9 either 1 or 0, since it is greater than 4, then it is rounded to and added to the first digit, all subsequent dots are rounded to zero
Hence 980 - - - - > 1000
Hence, estimated miles driven = 1000 miles
What i usually do is make a to do list on my phone and alarms of when i have time to do it
