Question

(ASAP NEED TO SUBMIT NOW!!!) What is the Unit Rate for each cyclist?

Answer 1

Answer:

Unit rates for cyclist A , B, C , D are 12 mile/ hour , 5 mile/hour, 9 mile/hour and 10 mile/hour respectively. Cyclist A is the fastest among the four.

Step-by-step explanation:

Cyclist A can ride 24 miles in 2 hours

so, cyclist A's  unit rate is, $\frac {24}{2}$

                                       = 12 mile/hour

Cyclist B's unit rate is, $\frac {5}{1}$

                                 = $\frac {10}{2}$

                                 = $\frac {15}{3}$

                                =  5 mile/hour

Equation for cyclist C is, y = 9x ,

so, cyclist C's unit rate is , 9 mile/hour

Slope of the graph for cyclist D,

= $\frac {10 -0}{1 - 0}$

 = 10

So cyclist D's unit rate is, 10 mile/hour

So, cyclist  A is the fastest.
