The unit rate is meters per hour.

Answer 2

`2 (1)/(2) \text{ hours} \longrightarrow 21 (3)/(4) \text{ meters}`


`1 \text{ hours} \longrightarrow 21 (3)/(4) / 2 (1)/(2) \text{ meters}`


`1 \text{ hours} \longrightarrow (87)/(4) * (2)/(5) \text{ meters}`


`1 \text{ hours} \longrightarrow (87)/(10) \text{ meters}`


`1 \text{ hours} \longrightarrow 8(7)/(10) \text{ meters}`

Answer: The unit rate is 8 7/10 meters/hour
