Answer 1

The unit rate for Herd A is 1.5 miles per hour and the unit rate for Herd B is 1.67 miles per hour

herd B travels faster

Which herd travels faster?

From the question, we have the following parameters that can be used in our computation:

The table and the graph

Where, we have

Table (Herd A)

Time(Hours) 2 4

Distance (miles) 3 6

The rate is calculated as

Rate = Distance/Time

So, we have

Herd A = 6/4

Herd A = 1.5 miles per hour

Graph (Herd B)

Time = 6

Distance = 10

The rate is calculated as

Rate = Distance/Time

So, we have

Herd B = 10/6

Herd B = 1.67 miles per hour

This means that herd B travels faster
