write the trip as a fraction in lowest terms 38 minutes to 4 hours
To convert 4 hours and 38 minutes to a fraction in lowest terms, we need to first convert the hours to minutes. Since there are 60 minutes in 1 hour, we have:
4 hours = 4 * 60 = 240 minutes.
So the total trip time is 240 + 38 = 278 minutes.
Now we can write the fraction as 278/60. However, this fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which in this case is 2.
So the simplified fraction is (278/2)/(60/2) = 139/30.
Therefore, the trip time is 139/30 in lowest terms.
