Answer:

3. Gwen’s sister has 151.2

4. It will take Joy 25 weeks for her to buy the new cellphone

5. 108.6 miles/hour

Step-by-step explanation:

Number 3:

Divide G-(604.80) by 4. Answer will be the amount of money Gwen’s sister have.

Number 4:

Divide the price of the cellphone (14,552.75) and the allowance Joy is trying to save (582.11). Answer will be how many weeks that will take Joy to buy the cellphone.

Number 5:

135.75 – distance covered by Sallie on her trip

1.25 hours – time that took Sallie to reach her destination

Formula that will be used: speed = distance ÷ time

N= 135.75 ÷ 1.25

Answer will be Sallie’s average speed to reach her destination.

5. Yesterday, Sallie took a trip to visit some family. She covered a total of 135.75 miles without making any stops along the way, and it took her exactly 1.25 hours to arrive at her destination. At what average speed did she arrive?​

Use the formula speed=distance/time to calculate the speed:

  • [tex]\sf{speed = \dfrac{distance}{time} }[/tex]
  • [tex]\sf{speed = \dfrac{135.75}{1.25} }[/tex]
  • [tex]\sf{speed = \boxed{\sf{\green{108.6}}} }[/tex]

The average speed is 108.6 miles per hour.
