About #160# miles

The key word here is "estimate".

As a quick estimate we would not use the exact values but easy values close to the actual values. Multiples of #10# are often good enough.

#83# is about #80# and #77# is also close to #80#.

So we could say he drove about #80# miles on each journey, giving us an estimate of about #160# miles in total.
