Answer:
The speed of the plane is 150 miles per hour, while the speed of the car is 50 miles per hour.
Step-by-step explanation:
Since a plane can fly 450 miles in the same time it takes a car to go 150 miles, if the car travels 100 mph slower than the plane, to find the speed (in mph) of the plane the following calculation must be performed:
450 to 150 is equal to 3: 1, that is, the plane travels three times the distance of the car.
Therefore, since 100/2 x 3 equals 150, the speed of the plane is 150 miles per hour, while the speed of the car is 50 miles per hour.

Answer: 5.5 seconds
Since the penny is dropped and not thrown, the initial velocity is 0 and the initial height is given as 150m. Plugging these into the given equation result in 
. To find how long it will take for the penny to hit the ground we set the equation equal to zero and solve for t. Since this doesn't factor, you'll need to use the quadratic formula:
. Since time cannot be negative, the answer will be the positive 5.5 seconds.
Answer:
2.5h = 150 min.
Step-by-step explanation:
An hour is 60 minutes.
A half an hour is 30 minutes.
Two hours = 1 hour + 1 hour = 60 minutes + 60 minutes = 120 minutes
2.5 hours = 2 hours + 1/2 hour = 120 minutes + 30 minutes = 150 minutes
2.5h = 150 min.
Hope this helps.
