Based on the speed that Jen used going to Cape Cod and then back to Boston, the average speed was 40 mph.

What was her average speed?

This can be found as:

= (Speed going to Cape Cod + Speed coming back) / 2

Speed coming back was:

= 60 / 3

= 20 mph which was why she took three times as long.

Average speed is therefore:

= (60 + 20) / 2

= 40 mph

In conclusion, her average speed was 40 mph.
