Answer:
The time taken by Macro to cover 200 m at the speed of 45 meter per minute is 4.44 minutes
Step-by-step explanation:
Given as :
The speed at which Macro swim = s = 45 meter per minute
The total distance cover by Macro = d = 200 meter
Let The time taken by Macro to cover 200 m = t minutes
<u>Now, From formula </u>
Distance = Speed × time
Or, d = s × t
Or, t = 
Or, t = 
Or, t = 4.44 minutes
So, The time taken by Macro to cover 200 m = t = 4.44 minutes
Hence The time taken by Macro to cover 200 m at the speed of 45 meter per minute is 4.44 minutes . Answer
