Formula to calculate amps per hour?

Is it possible to use a formula to calculate the approximate number of amps per hour this pair of lights will use?

Of course. What size battery does an ATV have? 12 volts?

Two 35 watt bulbs is 70 watts.

Power = volts times amps.

This yields 5.8 amps at 12 volts, 5.14 amps at 13.6 volts.

Based on your other posts (you really should have combined them all into one post), with your 10 amp hour battery you will get somewhere between one and two hours of light.
