If your Aunt Mary lived 100 miles from you (by car), how fast (miles per hour) should you drive your car (on average) to get to her house in 2 hours?
Choose the best answer from the options below:
A 25
B 50
C 75
D 100
E 150
B. 50
To calculate the speed (miles per hour), we need to divide the distance by the time.
In this case, the distance is 100 miles and the time is 2 hours.
Therefore, the speed (miles per hour) should be calculated as:
Speed = Distance / Time
Speed = 100 miles / 2 hours
Speed = 50 miles per hour
So, the correct answer is B) 50.
