Q1. ben travelled by car from his house to the airport. the airport is 180 miles away from his house and he drove at an average speed of 40 mph. if ben left his house at 11am, what time did he get to the airport? q2. a goose that swam 20 metres in 40 seconds. calculate the speed. give appropriate units with your answers.

For Q1.  If Ben is traveling 40 mph and he is driving to a destination 180 miles away, you will divide 180 by 40 to find out how many hours it took for him to get there.  Doing that division gives you 4.5 hours.  If he left his house at 11, then 4.5 hours later has him arriving at the airport at 3:30 pm.  For Q2. this is a unit rate problem.  If the goose can swim 20 meters in 40 seconds, you will divide 20 by 40 to find out how fast he is moving in meters per second.  20/40 = .5.  That means that the goose can travel .5 meters per second.

Answer: r=4.5  feetexplanation: radius  r  is half of the diameter  d,⇒r=d2=92=4.5  feetidk i could be wrong
