Let h represent the number of hours Liam must ride to beat his record.

distance-ridden + distance-to-ride ≥ record-distance
distance-ridden + (speed × time-to-ride) ≥ record-distance
  4 +7h ≥ 32 . . . . . . . . an inequality representing the distance Liam wants
  7h ≥ 28 . . . . . . . . . . subtract 4
  h ≥ 4 . . . . . . . . . . . . . divide by 7
