Answer 1

The time taken for a distance of 80 miles is 1 hour, which is the value which completes the table.

Since, the table exhibits a proportional relationship, we can create a proportional expression in the form ;

• y = kx ; k = proportionality Constant

Using the point (1/4, 20) :

20 = 1/4 × k

20 = k/4

k = 80

The relationship is : y = 80x

Time taken for a distance of 80 miles ;

• The value of y = 80

80 = 80x

x = 80/80

x = 1

Hence, the time taken for a distance of 80 miles is 1 hour.
