Question

An oval shaped walking path at a local park is 3/4 of a mile long. Four walkers recorded the number of laps they walked and the time it took them in them.

laps Minutes

Amber. 3. 40. Bruno. 4. 54. Cady. 5. 75. Drake. 6. 72.


Match each walker to their corresponding unit rate in miles per hour................................................. 3 3/4 mph, 3 mph, 3 1/2mph, 3 1/4 mph, 3 3/8 mph and 3 2/3mph

Answer 1

• Amber = 3 3/8 mph
• Bruno = 3 1/3 mph
• Cady =3 mph
• Drake = 3 3/4 mph

Explanation:

Consider the calculations in the table below with the respective columns being: Name | Laps | Time | Time(in hours) |Total Distance | Unit Rate

`\left|\begin{array}c---&---&---&----&----&---\\Amber&3&40&(40)/(60)&3*(3)/(4)=2.25&2.25 / (40)/(60)= 3(3)/(8) \\\\Bruno&4&54&(54)/(60)&4*(3)/(4)=3&3 / (54)/(60)= 3(1)/(3)\\\\Cady&5&75&(75)/(60)&5*(3)/(4)=3.75&3.75 / (75)/(60)= 3 \\\\Drake&6&72&(72)/(60)&6*(3)/(4)=4.5&4.5 / (72)/(60)= 3(3)/(4) \end{array}\right|`

We can then match each walker to their respective unit rates in miles per hour.

• Amber = 3 3/8 mph
• Bruno = 3 1/3 mph
• Cady =3 mph
• Drake = 3 3/4 mph
