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 =

Number of Cubes in 3 bowls =

4. Distance ran by Zebra = 420 ft

Time taken = 7 seconds

Speed = =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 = yards per min

6. Cost of 3 pounds of apple = $4.50

Cost of 1 pounds of apple = =$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
