Mr Timely drove 19 miles to his office in 1/2 hour. What was his average driving speed in miles per minutes? Express your answer as a common fraction.
1/2 hour = 30 minutes
19/30
jon drove 843 miles and rick drove four times as many miles how many miles did rick driv
To find Mr. Timely's average driving speed in miles per minute, we need to divide the total distance he traveled by the total time it took him to drive that distance.
In this case, Mr. Timely drove 19 miles in 1/2 hour. To express the time in minutes, we multiply 1/2 by 60 since there are 60 minutes in 1 hour.
(1/2 hour) * (60 minutes/1 hour) = 30 minutes
So, Mr. Timely drove 19 miles in 30 minutes, and to find the average speed, we divide the distance by the time:
Average speed = distance / time
= 19 miles / 30 minutes
To simplify this fraction, we divide both the numerator and denominator by their greatest common divisor, which is 1:
Average speed = (19 miles / 1) / (30 minutes / 1)
= 19 / 30
Therefore, Mr. Timely's average driving speed in miles per minute is expressed as the common fraction 19/30.
