Ian wants to run 4 1/2 miles to get ready for his upcoming race. He has set up 3 markers the same distance apart to show how far he has run. How far apart are the markers?

1 1/2

Step-by-step explanation:

Given that:

Total miles to run = 4 1/2 miles

Number of same distance markers set = 3

The diatances between each marker :

Total distance / number of markers

4 1/2 ÷ 3

9 /2 ÷ 3

9 / 2 * 1 /3

= 9 /6

= 3/2 = 1 1/2

Hence, the distance between each marker = 1 1/2

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
