Question

Answer 1

0.65 hours @ one kilometer per hour

Answer 2

Answer 3

.65 * 60 minutes or 39 minutes.

Answer 4

what about the distance

Answer 5

Well in the problem statement, the only distance presented or referenced was 0.65 km.
A rate of 1 kilometer per hour means that if that rate is sustained for only 30 minutes for example, then one covers 30/60 of 1 kilometer or 1/2 kilometer in distance.

The basic equation in these rate problems is:
Rate * Time = Distance
