You could choose 100 kilometers per hour. Then it would be <span>27.77778 meters per second. </span>
Answer:
D= m/v. if D = 0.9 C.M m/720 = 648
Take your base x the height, than 1/2 it. The answer would be 300.
If the cyclist traveled 2/3 of his journey already, then the remainder would be 1/3 of his journey, which we know is 30 miles. Double that and we have the miles he traveled during the first 2/3, 60. Then divide 60 by the miles per hour, 12, to get 5 hours. Add in the 3 hours from the remaining 1/3 of the journey and you have your total; the cyclist's trip took 8 hours.
