1. 4.8 x 10^9
2. 2 x 10^6
Answer:
to find the mean you must add all of the numbers in a data set together and then divide by how many numbers there are.
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
Substitute 21 for x.
y = 21 - 4 = 17
