during the first second of take off a rocket travelled 208 km in 50 mins at a constant rate suppose a penny is dropped from a sk
yscraper and could travel 153 km in 1/2 an hour at a constant rate which of these have a faster unit rate per hour ? how much faster?
2 answers:
56.4 km/ hr is the answer
Answer:
The penny :- 56.4 km/hr faster.
Step-by-step explanation:
Rate per hour of the rocket = (208 * 60) / 50 = 249.6 km/hr.
Rate per hour for the penny = 153 * 60 / 30 = 306 km/hr.
The penny travels faster by 306 - 249.6
= 56.4 km/hr.

I believe the answer is x=120
I cannot do that unfortunately
18(x)=100×43.
18(x)=4300.
Now divide both sides by 18. The number is x=238<span>.</span>
In this scenario, we can use the laws of cosines. When using the law of cosines, you will get
