A truck driver drive 49 miles in 1 1/3 hours. What was the average speed in miles per hour for this trip? Write the answer as a mixed fraction.
36 3/4
36 3/4
speed = distance / time
= 49/(4/3)
= 49(3/4)
= 147/4 or 36.75 mph
36 3/4
I still don't get it can you write out HOW to do it? :D
The (1, 49) represent 49 miles in 1 hour what is the equation?

To find the average speed in miles per hour, you need to divide the total distance traveled by the total time taken.
In this case, the truck driver drove 49 miles in 1 1/3 hours. To make the calculation easier, let's convert 1 1/3 hours into an improper fraction.
To do this, we multiply the whole number (1) by the denominator of the fraction (3), and then add the numerator (1):
1 * 3 + 1 = 4
So, 1 1/3 hours is equal to 4/3 hours.
Now we can calculate the average speed by dividing the total distance (49 miles) by the total time (4/3 hours):
49 miles ÷ 4/3 hours
To divide by a fraction, we multiply by its reciprocal. So, we can rewrite the calculation as:
49 miles * 3/4 hours
Now, multiply the numerator by the numerator and the denominator by the denominator:
49 * 3 = 147
1 * 4 = 4
The result is 147/4.
To simplify the fraction or write it as a mixed fraction, you divide the numerator by the denominator and write the remainder as a fraction over the denominator.
147 ÷ 4 = 36 with a remainder of 3
So, the average speed is 36 3/4 miles per hour.
