Major changes in biodiversity
You will need to turn this into scientific notation, so:
1.176 × 10^1 cm^2
To two significant figures means to two digits so since 7 is greater than 5, you will need to round up.
Final answer is:
1.2×10^1 cm^2
The average speed of the runner is 8.7m/s.
Therefore, Option C) 8.7m/s is the correct answer.
Given the data in the question;
Distance covered; 
Time taken; 
Average speed; 
Speed is the rate at which an object covers a certain distance. It is expressed as:

Where s is speed, d is distance and t is time taken.
We substitute our given distance into the equation

The average speed of the runner is 8.7m/s
Therefore, Option C) 8.7m/s is the correct answer.
