Answer:
45 mph
Step-by-step explanation:
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.
i did 4 1/2 miles or 4.5 ÷1/10 or .10=45mph
260/500 = 130/250 = 26/50 = 13/25
you put the amount flown over the total amount and then factor from there! i first divided the 260 and 500 by 2 (since both of the numbers are divisible by 2), which gave me 130/250. then divided by 5, and lastly by 2. final answer, reduced completely, is 13/25. hope this helps!
