Answer:
Riley did better than Darby because One-half < Three-fifths.
Step-by-step explanation:
The statement that explains which girl did better would be that
Riley did better than Darby because One-half < Three-fifths.
There are a total of 60 minutes in an hour, If we multiply each of these fractions by 60 minutes it would give us the exact number of minutes that each girl took to finish the race.
Riley: * 60 = 30 minutes
Darby: * 60 = 36 minutes
Therefore, we can see that it took Riley 6 minutes less than Darby to finish the race meaning that she had the better result.
Answer:
51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.
Step-by-step explanation:
Given:
75 feet/second.
Now, to convert 75 feet/second into miles/hour.
So, to convert we divide the value of feet per second by conversion factor to get miles per hour.
Value of feet per second = 75.
Conversion factor = 1.4667.
Now, putting the formula to get the value in miles/hour:
Value in miles/hour = value of feet/second ÷ conversion factor.
Value in miles/hour =
=
<em>Rounding nearest to whole number = 51 miles/hour.</em>
Therefore, 51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.
