Julia and Kajal make deliveries on their bicycles. For each delivery, they need some time to get ready, and then they each ride at a constant speed.
Julia takes 404040 minutes to make a delivery 555 kilometers away. She uses 101010 minutes of the delivery time to get ready.
The following equation gives the time it takes Kajal to make a delivery (in minutes) as a function of the distance of the delivery (in kilometers).
t = 15+6dt=15+6dt, equals, 15, plus, 6, d

Answer from: Quest
56.6
step-by-step explanation:
the ratio of the perimeters is equal to the scale.
the ratio of the areas is equal to the square of the scale.
34 / 20 = k
a / 19.6 = k²
substituting:
a / 19.6 = (34 / 20)²
a = 19.6 (34 / 20)²
a ≈ 56.6
