Jamal ran 8 kilometers, sprinted 500 meters, and climbed bleachers for a distance of 1.5 kilometers during track practice. How m

stiv31 [10]

Answer: $10,000\ meters$

Step-by-step explanation:

In order to calculate the total meters Jamal traveled during the practice, you need to make the conversions from kilometers to meters.

You need to remember that:

$1\ km=1,000\ m$

Therefore:

$(8\ km)(\frac{1,000\ m}{1\ km})=8,000\ m$

$(1.5\ km)(\frac{1,000\ m}{1\ km})=1,500\ m$

Finally, you can solve the following addition in order to get the total meters Jamal traveled during the practice. The sum is:

$total=8,000\ m+500\ m+1,500\ m\\\\total=10,000\ m$
