.) Rhianna is training for a marathon. She is now able to run 4 5/6 miles in ½ hour. What is Rhianna's rate in miles per hour? Express your answer as a mixed number and include the rate statement in the end.

Respuesta :

Answer:

9 2/3 miles /hour

Step-by-step explanation:

Rate can also be referred to as speed.

The formula for Rate or Speed = Distance(Miles) /Time(hours)

Rhianna's distance = 4 5/6 miles

Rhianna's Time = 1/2 hour

Rate = 4 5/6 miles/ 1/2 hour

Rate = 29/6 miles ÷ 1/2 hour

Rate = 29/6 × 2/1

Rate = 29/3 miles/hour

Rate = 9 2/3 miles /hour

Rhianna's rate = 9 2/3 miles /hour
