Question

During a practice race, Mario's average time for completing a lap was 1 minute, 15 seconds. Danica's average lap time was 1 minute, 12 seconds. The practice race was 80 laps. Who won the race? By how many minutes did that person win?​

Answer 1

Danica won the race by 4 minutes.

Step-by-step explanation: Hope this helps. Have a nice day. Mario’s average lap time is 1 minute and 15 seconds, which is equivalent to 75 seconds. For 80 laps, Mario’s total time would be 80 laps * 75 seconds/lap = 6000 seconds.

Danica’s average lap time is 1 minute and 12 seconds, which is equivalent to 72 seconds. For 80 laps, Danica’s total time would be 80 laps * 72 seconds/lap = 5760 seconds.

Therefore, Danica won the race.

To find out by how many minutes Danica won, we need to convert the difference in their total times from seconds to minutes. The difference in their total times is 6000 seconds - 5760 seconds = 240 seconds. Converting this to minutes gives us 240 seconds / 60 = 4 minutes.

So, Danica won the race by 4 minutes.
