Write the answers to the following questions in scientific notation. a. The velocity of a jet plane is 1.1 x 103 miles per hour, and the escape velocity of a rocket from Earth is 22.7 times the plane's velocity. Find the rocket's velocity by computing 1.1 x 10 22.7. x 10 miles per hour b. Earth travels 6.21 x 108 miles around the Sun each year in approximately 9 103 hours. Compute (6.21 108) + (9 x 103) to determine Earth's speed in miles per hour. 6.9 10 miles per hour Write the answers to the following questions in scientific notation. a.
