Question

Jason can travel 24 3/4 miles is 1/2 hour. what is his average speed in miles per hour?

Answer 1

Answer: $\text{Average speed}=49\dfrac{1}{2}$ miles per hour

Step-by-step explanation:

Formula to find the average speed is given by :-

$\text{Average speed}=\dfrac{\text{Distance}}{\text{Time}}$

Given : Distance = $24\dfrac{3}{4}$ miles=$\dfrac{24\times4+3}{4}$ miles

$=\dfrac{99}{4}$ miles

Time =$\dfrac{1}{2}$ hour

Then, $\text{Average speed}=\dfrac{\dfrac{99}{4}}{\dfrac{1}{2}}$

i.e. $\text{Average speed}=\dfrac{99\times2}{4}=\dfrac{99}{2}$

i.e. $\text{Average speed}=49\dfrac{1}{2}$ miles per hour

Answer 2

24 3/4 miles is the distance
1/2 hour - is time
V=S/t
24$\frac{3}{4}$  / 0.5 = $\frac{(24*4+3)2}{4}$=49.5  miles per hour
