Answer:
450 miles
Explanation:
This is a direct variation. Such a relationship exist between the miles covered and the time taken that an increase in one results in an increase in the other and vice versa.
Given that she can ride her skateboard 2 miles in 10 minutes
Let the distance be d and the time t
d∝t,
d = kt where k is the constant of proportionality
10 = 2(k), k = 5
d= 5t
if she rides her skate board in 1.5 hours, the distance she will cover
d = 5(1.5 × 60) to convert the time given from hours to minutes
d = 450 miles
