John is baking rectangular cakes. The first cake he baked was 3 inches wide and 5 inches long. The second cake he baked was 6 inches wide and 10 inches long. The third cake he baked was 12 inches wide and 20 inches long. If John continued this pattern, what would the dimensions of his fourth cake be?

24x40

Everytime the dimensions double, so the forth time the dimensions would be:

24 wide, 40 long.

24 in wide and 40 in  long.

Step-by-step explanation:

Each dimension is doubled:

width 3 goes to 6, and 6 goes to 12.

length 5 goes to 10, and 10 goes to 20.

So 4th cake will have dimension 2*12 and 2*20 in.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
