Question

mr kirk drove 164 miles in the morning and 219 miles in the afternoon .estimate the total number of miles she drove that day

Answer 1

This is more math than it is English but let's see. She drove 164 miles in the morning and 219 miles in the afternoon.
219+164=383
So from what is given it can be estimated that Mr Kirk drove about 383 miles that day.

Answer 2

The other answer is correct but it hasn't been estimated. So, 164 estimated is 160, 219 estimated is 220. So add 160 and 220 and you should get 380.
