So there are 60 minutes in an hour, so we convert. Then we find out we have 90 minutes so we do 2×9 so the answer is 18 miles
Answer:
450 miles
Step-by-step 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
