____________________speed_______time_______distance
Normal______________(___)_______4&1/2______270
Faster______________(___)_______3__________270

Use the definition of "speed", being distance divided by time.

____________________speed_______time_______distance
Normal______________270%2F4%261%2F2_______4%261%2F2______270
Faster______________270%2F3_______3__________270


Just compute the difference in speeds.
270%2F3-270%2F4%261%2F2
