Allen drove 90 miles in 2 and 1/4 hours at a constand speed, how many miles did he drive in one hour.
90 miles in 2.25 hrs
x miles in 1 hr
90/x = 2.25/1
2.25x = 90
x = 90/2.25 = ...
195 mph
To find out how many miles Allen drove in one hour, you can use the concept of speed, which is defined as distance divided by time.
In this case, Allen drove 90 miles in 2 and 1/4 hours. To convert the time to a fractional form, we need to express 1/4 as a decimal. 1/4 is equal to 0.25, so the total time is 2 + 0.25 = 2.25 hours.
Now, you can calculate the speed by dividing the distance (90 miles) by the time (2.25 hours):
Speed = Distance / Time
Speed = 90 miles / 2.25 hours
Dividing 90 by 2.25, we find that Allen's speed is 40 miles per hour.
Therefore, Allen drove 40 miles in one hour.
