Answer:

3. 15 Cubes

4. 60 ft per sec , 180 ft

5. 58 yards per min

6. $7.50, $18.00

Step-by-step explanation:

3. Number of Cubes in 7 bowls = 35

Number of Cubes in 1 bowls = [tex]\frac{35}{7}[/tex]

Number of Cubes in 3 bowls =[tex] \frac{35}{7} \times 3 = 15[/tex]

4. Distance ran by Zebra = 420 ft

Time taken = 7 seconds

Speed = [tex]\frac{Distance}{time}= \frac{420}{7}[/tex]=60 ft per sec

Hence

Distance = speed x time

Distance covered in 30 seconds = 60 x 30 = 180 Ft

5. Distance travelled = 870 yards

Time taken = 15 mins

Speed =[tex] \frac{Distance}{time}= \frac{870}{15}=58[/tex] yards per min

6. Cost of 3 pounds of apple = $4.50

Cost of 1 pounds of apple = [tex]\frac{4.50}{3}[/tex]=$1.50

Cost of 5 pounds of apple = 5 x $1.50 =$7.50

Cost of 12 pounds of apple = 12 x $1.50 =$18.00
