Sanford's gym coach made him run 20 laps on a 600-m track. How many kilometers did he run? How many miles? Round your answers to two decimal places, if necessary miles. 

Answer:

Given sanford had to run 20 laps on a 600m track.

As he can run 600m in one lap,

therefore in 20 laps, he had run 20*600 = 12,000m distance.

Now we should remember that 1000m = 1km

Therefore, 12,000 = 12 * 1000m = 12km.

Also we should know that 1km = 0.621miles

Therefore 12km = 12 * 1km = 12 * 0.621 = 7.452miles

If we round 7.452 upto two decimal points, it becomes 7.45miles

Therefore, sanford run 12 km, which is 7.45 miles.
