Question

100 miles in 2.5 hours in unit rate ????

Answer 1

they are asking how far you can go in 1 hour (unit means one here)

Answer 2

yes

Answer 3

you could write it as a ratio

100/2.5 = x/1
which says: 100 miles is to 2.5 hours as x miles is to 1 hour

x/1 (x is the unknown rate) means x divided by 1, and is just x

x = 100/2.5

simplify 100/2.5
