Answer C. 2.00 Meters/second
1 kilometer = 1000 meter
1 hour = 3600 seconds
7.2 x 1000 = 7200
so 7200 meters an hour
or 7200 meters every 3600 seconds
7200/3600
we then want the 3600 to become one second to find meters per (1)second.
so 7200/3600 simplified = 2. 2 meters per second
answer C
25% of the circles are shaded. You would find this by dividing 3/12! Have a good day!
