Alex swims at an average speed of 45 mi./min. how far does he swim in one minute 24 seconds
kompoz [17]

Answer: Alex Swims 63 mi in one minute 24 seconds

Explanation:

Alex swims 45 miles in 1 minute so what we need to find is the 24 seconds.

You'd take 2 divided by 5 which is the simplified fraction of 24 seconds over 60 seconds

Simplifying the fraction to a decimal gives you 0.4 then multiply it by 45 giving 18.

45+18=63 mi
