Question

a car travels 68 miles per hour for 1 hour 55 minutes approximately how far does it travel

Answer 1

Ok, let’s start by rounding the 55 minutes to 60 minutes or 1 hour.
We can then add the rounded hour to the whole hour to make two hours.
Now that we have rounded and added to get a whole number, we can use multiplication as:
2 hours x 68 (miles per hour) = 136 miles as an approximate distance
