Speed and RPM indicator

Just a small question for the more technical minded.

What speed should your 2.5 be travelling at in 4th gear overdrive with a 3.45 diff, 25% higher ratio gearbox and rev-counter reading 4700rpm?

Reason for question is that I don't think my speedo is reading correctly with 195/60/14 tyres. 

The needle was pointing at my left foot 🤣
