Question

At his last track meet, jon ran the 400-meter dash in 54 seconds. his friend brenna bet him that he couldn't run a whole kilometer at that pace, but jon is determined to prove her wrong. how many minutes would he have to run at this pace to win the bet?

Answer 1

To win the bet, Jon would have to run for 2.25 minutes at the same pace as the 400-meter dash.

Step-by-step explanation:

To find out how many minutes Jon would have to run at the same pace to win the bet, we need to convert the distance he ran in the 400-meter dash to kilometers.

There are 1000 meters in a kilometer, so we divide 400 by 1000 to get 0.4 kilometers.

Since his time for 0.4 kilometers was 54 seconds, we can set up a proportion to find the time for 1 kilometer:

0.4 km / 54 s = 1 km / x s

Cross-multiplying, we have:

0.4x = 54

x = 54 / 0.4

x = 135

Therefore, Jon would have to run for 135 seconds to win the bet. Since 1 minute is equal to 60 seconds, we can divide 135 by 60 to convert seconds to minutes:

135 s / 60 s = 2.25 minutes

So, Jon would have to run for 2.25 minutes at the same pace to win the bet.
