ELI5: Why are flights from NYC to Boston 1.5 hours long when they should only take around 20-30 mins?

The flight distance from NYC to Boston is around 190 miles. Assuming a passenger jet can travel at 500mph, shouldn't it take only 20-30 minutes to travel the distance, instead of the usual 1-1.5 hours?

Flight times are counting "block time". This is the time from when the blocks are removed from the wheels of the plane at the gate and it can push back, to the time the plane enters the gate at the destination and has the blocks put back on its wheels to stay in place.

This means that taxiing time, waiting for take off clearance, etc., is all part of a flight time.
