Question

During the first seconds after takeoff, a rocket traveled 208 kilometers in 50 minutes at a constant rate suppose a penny is dropped from a skyscraper and could travel 153 kilometers in 1/2 hours at a constant rate. Which of these objects has a faster unit rate per hour? How much faster?

Answer 1

the penny travels at a faster rate by 56.4 kilometers

penny = 153 for 30 min

penny = 306 for 1 hour

rocket = 208 in 50 min

208/5 = 41.6 *6 = 249.6 in 1 hour

penny is faster by 56.4 kilometers
