5. A giraffe is twice as tall as its baby. The baby's height and the mother's height total 4.5m. How tall is the baby? How tall is the mother?

Step-by-step explanation:

call x the mother deer, y the baby deer, we have x = 2y

x + y = 4,5 ---> x = 3, y = 3/2

V = velocity
d = distance (or displacement)
t = time
(original equation)
v = d/t
(Given information)
v = 35m/h
d = 15m
(rearrange equation to get)
t = d/v
(substitute numbers in)
t = 15m/35m/h
t = 0.43hours

Therefore, it would take 0.43hours to drive 15 miles at 35 miles per hour

*Hope this helps*
