The streets of New York are arranged in a grid as shown in the diagram. There are three direct ways of travelling from A to B. Travel one block North followed by two blocks East Travel one block East followed by one block North followed byone block East Travel two blocks East followed by one block North. We write these as NEE, ENE and EEN respectively. There are six direct routes from A to C. Four of these routes are NNEE, NENE, ENEN and EENN. Write down the remaining two routes. and How many direct routes are there to travel from A to D? How many direct routes are there to travel from A to E? 30. Ten runners, numbered 5 to 14 inclusive, take part in a race. There were no tied positions.Winston watched the race but forgot to write down the positions of the runners. Fortunately Winston is a mathematician and he remembered one fact about the number of each competitor. List all possible numbers of the competitors in the spaces below. Hence complete the table showing the final positions in the race.1st Prime number 2nd Factor of 24 3rd Cube number 4th Multiple of 5 5th Factor of 187 6th Two-digit even number in which the first digit is smaller than the second 7th Two-digit number in which both digits are square numbers 8th Number which has exactly four factors 9th A square number 10th A number which is greater than 10 Position in race 1 2 3 4 5 6 7 8 9 10 Number of runner Time is Up!
