Thx u for plz answer one or all thx u very much

For number three you'll divide 60 by each person's seconds. Like this.

For Camille you will do this
60 ÷ 6 = 10
For Ariel you will do this
60 ÷ 2 = 30
Next you'll multiple what you got by their distance. Like this.
For Camille you will do this
10 × 16 = 160
For Ariel you'll do this
30 × 6 = 180
Next you'll subtract those two answers. Like this.
180 - 160 = 20
Your answer is Ariel's frog was faster and it was ahead by 20 centimeters.
