Answer:
Length 1 1/4 = 10 /8 = 10 cubes L
width = 5/8 = 5 cubes W
Height = 3/4 = 6/8 = 6 cubes H
10 x 5 x 6 = 300 little cubes
The distance covered by the hare and the tortoise in t seconds are 8t and 5t respectively. (Simple Speed-Distance-Time relation)
The tortoise gets a 510m headstart so at t=0 is 1490m.
The functions representing the distance of both of them from the finish line is,
F(x)=2000-8t,. for hare
G(x)=1490-5t,. for tortoise
