Ihave 15 minutes left on this test, i have the answers for the other question btw

Step-by-step explanation:

it is b

its hard to explain this is the graph

range is from the lowest y to the highest for this one is from negative infinity to positive 8

rate is 8 miles per hour and he travels 40 miles per 5 hours

Step-by-step explanation:

The story problem told that i should assume that 1 mile is 1.6 km

so 5km/hr is equal to 8m/h

i got it by multiplying 5 by 1.6 so i can change from the unit km to mile

so about the miles per 5 hours just multiply the 8 mph by 5 so it is 40

40miles per 5hrs

hope i made it clear
