Question

Janik plans to go to the gym a few times this week. She wants to work out on 10 different machines this week. If she spends a total of 4 hours at the gym this week, will she have enough time to spend at least 20 minutes on each machine?

Answer 1

Given that,

Janik plans to go to the gym a few times this week

She wants to work out on 10 different machines this week

she spends a total of 4 hours at the gym this week

To find will she have enough time to spend at least 20 minutes on each machine

Total time she spends this week in gym (in minutes)

we know that,

`1\text{ hour}=60\text{ minutes}`

we get,

`4\text{ hours}=4*60\text{ minutes}`
`=240\text{ minutes}`

If she spends at least 20 minutes on each machine,

Total time taken is 20 x Number of machines.

we get,

Total time taken is,

`=20*10=200\text{ minutes}`

Since, 200 minutes is less than 240 minutes.

Hence, She has enough time to spend at least 20 minutes on each machine.
