Question

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 skyscraper 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?

Answer 1

56.4 km/ hr is the answer

Answer 2

The penny :- 56.4 km/hr faster.

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.
