Melissa ran the 800 meter dash in 3 minutes and 8 seconds at the district track meet. Her goal was to run the race in 2 minutes and 45 seconds. How much faster did Melissa need to run to meet her goal?

Hey there! I'm happy to help!

There are sixty seconds in a minute. This means there are 180 seconds in 3 minutes, meaning that Melissa ran her race is 188 seconds.

2 minutes is 120 seconds, plus 45 gives us 165 seconds.

188-165=23

Melissa had to run 23 seconds faster to meet her goal.

Have a wonderful day! :D

She needs to run 23 seconds faster

Step-by-step explanation:

First convert from minutes to seconds

3 minutes and 8 seconds= 188 seconds

2 minutes and 45 seconds=165 seconds

Now subtract

188-165=23

She needs to run 23 seconds faster

Hope this helps :)
