The 'like' terms are the 16x and the 12x.
They can be combined to make a single term ... 28x .

<span>Speed
is calculated as distance covered, divided by the time taken to cover that
distance. In this case, the sales person covered 50KM in 45minutes (which can
also be expressed as 3/4 hours). To calculate the speed he used to cover this
distance, we divide the distance covered by the time taken. So 50km/3/4hours.
This gives us 66.67km/hr. In order to calculate the amount of time the
salesperson used to travel from the office to the sales person, we calculate
as follows 250km/66.67km/hr. This gives us a total of 3.75 hours or 3 hours 45 minutes.</span></span>
My Brain ish saying TRUE! ^-^
1 because the cant be anymore than 1 3/4 in the answer because 3/4 + 3/4 = 6/4 or 1 2/4. so i would take 1 and subtract 3/4 to 1/4 and 1/4 is less than 3/4
