Trips and reflections (II)
Here is another story about a bike ride:
|
Ned's ride lasted six and a half hours. At first he rode at a speed of 16 kilometers per hour, then slowed down to 12 kilometers per hour. The distance he rode during the first part of the ride is longer by 6 kilometers then the distance he rode in the second part.
Questions: After how long did Ned reduce his speed? What distance did
he ride in the first part of his trip?
