Answer:

65 kph

Step-by-step explanation:

There were a total of 7 hours. So two hours were at 70 and the other 5 hours at 63: the equation would be: (70+70+63+63+63+63+63)/7=65

Proportional Not Proportional 18/72 and 4/16

Ivan

The best way to answer this question is to simplify each faction individually. 18/72 can be reduced to 1/4, and 4/16 can be reduced to 1/4. Since both of these are the same fraction the are proportional.
