Julia exercises at the gym. For every 3 minutes she spends running, she spends 5 minutes lifting weights.

Which of the following could be how Julia spends time at the gym?

A Run for 10 mins and lifting weights for 12 mins.

B Run for 15 minutes and lift weights for 25 mins.

C Run for 20 mins and lift weights for 30 mins.

D Run for 24 mins and lift weights for 48 mins.

E Run for 30 mins and lift weights for 50 mins.

Answer:

B Run for 15 minutes and lift weights for 25 mins.

E Run for 30 mins and lift weights for 50 mins.

Step-by-step explanation:

Given:

Julia Spend s 3 minute for running and weight lifts for 5 mins.

We need to find which choices are correct match for the given data.

Hence we will check each.

A Run for 10 mins and lifting weights for 12 mins.

Since given that she runs for 3 mins and in the above choice the given date is she is running for 10 mins it is neither 3 nor multiple of 3.

Hence this is Choice is Incorrect.

B Run for 15 minutes and lift weights for 25 mins.

Now Given in choice is that she runs for 15 minutes and in given data she runs for 3 minutes hence 15 is multiple of 3 and is multiplied by 5 also given lift weights for 25 mins and in given data she lift weights for 5 mins since 25 is multiple of 5 and is multiplied by 5.

Hence the above Choice is Correct.

C Run for 20 mins and lift weights for 30 mins.

Since given that she runs for 3 mins and in the above choice the given date is she is running for 20 mins it is neither 3 nor multiple of 3.

Hence this is Choice is Incorrect.

D Run for 24 mins and lift weights for 48 mins.

Now Given in choice is that she runs for 24 minutes and in given data she runs for 3 minutes hence 24 is multiple of 3 and is multiplied by 8 also given lift weights for 48 mins and in given data she lift weights for 5 mins and 48 is not the multiple of 5.

Hence this is Choice is Incorrect.

E Run for 30 mins and lift weights for 50 mins.

Now Given in choice is that she runs for 30 minutes and in given data she runs for 3 minutes hence 30 is multiple of 3 and is multiplied by 10 also given lift weights for 50 mins and in given data she lift weights for 5 mins since 50 is multiple of 5 and is multiplied by 10.

Hence the above Choice is Correct.
