Answers
Answer:
75.5 or 71/200
Step-by-step explanation:
71 divided by 2 is 75.5, and 75.5 is equal to 71/200.
Answer:
71:120
Step-by-step explanation:
Time taken by Stephen to complete one set =71 minutes
Time taken by Bridget to complete one set = 2 hours
Since the time taken by the two are in different units we can't find the ratio. In order to find the ratio we have to bring the two into same units ie in minutes (for our convenience).
Time taken by Bridget in minutes to complete one set=2*60=120 minutes
Ratio of the time take by Stephen to Bridget is
=71:120
PS: The same question can also be solved by bringing the time into hours, seconds or any other unit of time by multiplying it with the respective values. The answer would still remain the same and is invariant of the common units in which its expressed as.
Hope this helps.
