Last month, Jasmine's family drove to a resort in the mountains. They drove 240 mi. On the first day of the trip. On the second day, they drove 205 mi., and on the third day, 315 mi. On the fourth day, before arriving at their final destination, they drove 220 mi. Use front-end estimation to find a reasonable estimate of the total number of miles Jasmine's family drove to reach their vacation destination.

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

well, if it's triangular garden, the triangle could represent the garden.
