The question is identical to the one I just gave on ages

The distance from my house to Luton is 50 miles
The distance from my house to Southampton is 200 miles

How many times further away is Southampton than Luton

9.3 x 10 (to the power of 7) = 93000000

93000000 divided by 250000 = 372

372 in standard form is 3.72 x 10 (to the power of 2)

The answer should, if I'm correct, be 3.72 x 10 (to the power of 2)
