a.give the answer in meters

b.give the answer in centimeters

needddd help anyone???

Answer 1

r=20
t=b
he needs to walk 20-b meters
i don't really know metric system too well, so I can't really help with the cm part... but im guessing its 20-b(100) because isn't 100cm=1m?

Answer 2

x=distance that the turtle needs to walk to catch up the rabbit

a/. x=20-(b/100)
b/. x=20*100-b
