T1 = S / V1 T2 = S / V2 where S the distance is the same in both cases
V1 T1 = T2 V2 = (T1 + x) * (V1 + 10)
V1 T1 = V1 T1 + x V1 + 10 T1 + 10 x
x (V1 + 10) = -10 T1
x = 10 T1 / (V1 + 10) where x is the time that would be saved
x = 28 / (100 + 10) = .254 hrs or 15.3 min
Check: 2.8 * 100 = 280 km
2.55 hrs * 110 = 280 km
