Question

Jason drove 275 miles in 5 1/2 hours. What was his average speed in miles per hour ?

Answer 1

50 mph because the equation for your problem is distance over time. Then you put 275 on top and divide it by 5.5. 

Answer 2

$v=\dfrac{s}{t}\\\\s=275mi\\\\t=5\dfrac{1}{2}h=5.5h\\\\v=?$


substitute

$v=\dfrac{275}{5.5}=50mph$

Answer: 50mph.
