ab is 26.If abb x 7 = 18ba then a = 2 (if a = 1 then the maximum value of abb is 199, and 7 x 199 = 1393 : if a ≥ 3 then the product would start with a '2' or higher number)The equation now becomes 2bb x 7 = 18b2b is therefore an even number such than 7 x b has a final digit of 2. The only number that satisfies this condition is 6 so that 7 x 6 = 42.a is 2 and b is 6.

I can't answer for others who may read this question, but I know for a fact that mine is not, since 20 meters is about 66 feet.
5km is 5000mPrefix 'kilo' is used to denote multiples of meter and uses factor 103 or 1000.In order to convert kilometers to meters value in kilometers have to multiplied by provided factor: 5 kilometers = 5 * 103 = 5 * 1000 = 5000 meters5 kilometers = 5,000 meters.50005000 now leave me alone5000 meters5km = 5000m5000There is 5000 meters in 5 kilometers.5000 meters5000, kilo means 1000 so you can read it as 5 'thousand' meters
