A lab-created weed that grows at a very fast rate. It can grow up to 0.75 ft per day. How fast in inches per hour can the weed grow? Show your work using the correct conversion factors.

1 mile = 5280 feet
1 foot = 12 inches
1 day = 24 hours
1 hour = 60 minutes

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
