GPT 3.5 · Answer

The average speed on the first route can be calculated by dividing the distance by the time:

Average speed on first route = 400 miles/8 hours = 50 mph

The average speed on the second route can be calculated in the same way:

Average speed on second route = 420 miles/7 hours = 60 mph

The average speed on the faster route is 60 mph and the average speed on the slower route is 50 mph. Therefore, the average speed on the faster route is 10 mph higher.
