Answer:
142.24cm
Step-by-step explanation:
If 100 inches = 254cm then if you do 254/100 you will get how many cm are in an inch. 254/100 = 2.54
This means there are 2.54 cm in an inch. Multiply 2.54cm by 56 inches and you get how many cm are in 56 inches which is 142.24cm. This means Elena is 142.24 cm tall.

1/3 of 45 is 15, but 160 * .12 is 19.2,
1 minute = 60 seconds
1 hour = 60 minutes = 60*60 seconds = 3600 seconds
1 hour = 3600 seconds
Multiply both sides by 2.1 to get
1 hour = 3600 seconds
2.1*(1 hour) = 2.1*(3600 seconds)
2.1 hours = 7560 seconds
Now use the formula below
d = r*t
where,
d = distance
r = rate or speed
t = time
In this case,
d = unknown
r = 4 ft per sec
t = 7560 seconds (equivalent to 2.1 hours)
So,
d = r*t
d = 4*7560
d = 30240
The bird can travel 30240 feet. Convert this to miles by dividing the value by 5280 (since 1 mile = 5280 feet)
30240/5280 = 5.727 roughly which rounds to 5.7
Answer: C) 5.7 miles
