Answer:
21/20
Step-by-step explanation:
a) One hour is equivalent to 60 minutes.
So we can multiply 50 minutes by the fraction [tex]\frac{1 hour}{60 minutes}[/tex], so we could convert 50 minutes to hours.
It is:
[tex]50 minutes * \frac{1 hour}{60 minutes}=\frac{50}{60}hours[/tex]
If we simplify the fraction, we have:
[tex]50 minutes = \frac{5}{6}hours[/tex]
b) In order to express the turtle's speed in miles per hour, we have to divide
[tex]\frac{7}{8}miles[/tex] by [tex]\frac{5}{6}hours[/tex]
So:
[tex]\frac{\frac{7}{8}miles }{\frac{5}{6}hours }[/tex]
We simplify the expression by multiplying 7 mile by 6 and 8 by 5 hours:
[tex]\frac{\frac{7}{8}miles }{\frac{5}{6}hours}=\frac{42 miles}{40 hours} =\frac{21 miles}{20 hours}[/tex]
Answer:
a) when changing 50 minutes to hours get fraction [tex]\dfrac{5}{6}[/tex]
b) [tex]\text{Unit rate of turtle }=\dfrac{21}{20}[/tex] miles per hour
Step-by-step explanation:
A turtle walks [tex]\dfrac{7}{8}[/tex] of a mile in 50 minutes.
Unit rate of turtle in miles per hours.
Unit rate means number of miles cover in 1 hours.
Distance = [tex]\dfrac{7}{8}[/tex] miles
Time = 50 minutes
1 minute =[tex]\dfrac{1}{60}[/tex] hour
50 minutes =[tex]\dfrac{1}{60}\times 50[/tex] hours
[tex]\text{Unit rate of turtle }=\dfrac{7/8}{5/6}[/tex]
[tex]\text{Unit rate of turtle }=\dfrac{21}{20}[/tex] miles per hour
Part a)
[tex]\text{Unit rate of turtle }=\dfrac{21}{20}[/tex] miles per hour
when changing 50 minutes to hours get fraction [tex]\dfrac{5}{6}[/tex]
Part b)
Unit rate of turtle is ratio of distance covered per unit of hours.
[tex]\text{Unit rate of turtle }=\dfrac{21}{20}[/tex] miles per hour
