(Refer to Figure 74.) Using the scale on the sectional chart excerpt, the distance between the two depicted airports is approximately 30 nautical miles. Maintaining a groundspeed of 90 knots, the estimated time en route is

During a VFR cross-country flight using pilotage and dead reckoning, you observe that prominent topographic features (checkpoints) are passing 20% faster than planned, indicating your ground speed is 20% higher than the planned 100 knots. There are 100 nautical miles remaining to your destination. Your best estimate of the remaining time en route is
