Answer:

120 minutes or 2 hours

Step-by-step explanation:

We know that it takes a car 30 minutes to travel 45 km so

30 m : 45 km

?  m : 180 km

180 ÷ 45 = 4

30 × 4 = 120

45km : 30 min = 180km : x

x = \frac{180*30}{45} = \frac{180*2}{3} = 60*2 min = 120 min = 2h

And adult had 1900 times more cells than a newborn. Or if you want to put it in scientific notation it would be 1.9 • 10^3
