Answer :
We are given that 2 people, John and Bob, travel a distance of 4 miles and 2 miles respectively. To determine which of the two went faster, we need to find the ratio of distance per time for each individual.
For Jhon we have:
[tex]\text{rate}=\frac{distance}{time}[/tex][tex]\text{rate}=\frac{4\text{miles}}{1\text{hour}}=4\frac{\text{miles}}{\text{hour}}[/tex]For bob we have:
[tex]\text{rate}=\frac{2\text{mile}}{(\frac{1}{2})\text{hours}}=4\frac{miles}{\text{hour}}[/tex]Therefore, John and Bob had the same speed.
