Answer:
Answer to this is long and verbal - see below. Short answer is "yes, he can make it"
Step-by-step explanation:
We need to average his time per length (assuming he never gets tired!)
93/3 = 31 secs per length
Now figure 100 lengths using this average
100 x 31 sec - 3100 secs
Convert secs to minutes.
3100 / 60 secs per minute = 51.66 mins needed to complete.
This is under 55 minutes, so we assume he can make it!
The given information is correct he could swim 100 lengths in under 55 minutes.
Given that
Donald swims 3 lengths of a swimming pool in 93 seconds.
Use this information to show that he could swim 100 lengths in under 55 minutes.
According to the question
Donald swims 3 lengths of a swimming pool in 93 seconds.
Then,
The measure of length per second is,
[tex]\rm = \dfrac{93}{3}\\\\=31 \ length \ per \ second[/tex]
He can swim 31 lengths per second.
Therefore,
The minutes he can swim 100 lengths is,
[tex]\rm = 100 \times 31\\\\= 3100 \ seconds[/tex]
To convert seconds into minutes divided by 60.
[tex]\rm = \dfrac{3000}{60}\\\\= 50 \ minutes[/tex]
Hence, the given information is correct he could swim 100 lengths in under 55 minutes.
