The 60 minute rule you refer to is for NVFR aircraft planning to an aerodrome not served by a navaid. AIP ENR 1.1 58.3.3
So how would you answer it? I had same KDR for this question and I figure 25 min flight to leave reserves intact you have to divert now in this scenario, 70-25 = 45, I believe question was essentially the same in exam being time to alternate left you right on min fuel
