Question

The McBride drove 317 miles on one day and 289 miles on the next day estimate the number of miles the McBride drove during the two days

Answer 1

an estimation is not exact..

317...rounds to 300
289...rounds to 300
                        --------add
        total :        600 (estimation) <==

actual miles driven is : 317 + 289 = 606

Answer 2

Answer: There are 610 miles the McBride drove during the two days.

Step-by-step explanation:

Since we have given that

Number of miles the McBride drove on one day = 317 miles

Number of miles the McBride drove on next day = 289 miles

Using estimation we get that

317 → 320

289 → 290

So, Number of miles he drove during the two days is given by

$320+290\\\\=610\ miles$

Hence, there are 610 miles the McBride drove during the two days.
