Step-by-step explanation: divide by the amout of time in 2 hour and thats how many hours it take to walk that many miles.
Answer:
- His speed is 3 miles per hour.
- He can cover three more miles in 4 hours than he can in 3 hours.
Step-by-step explanation:
We know that speed is defined as the ratio of distance over time.
i.e.
[tex]Speed=\dfrac{distance}{Time}[/tex]
It is given that:
The distance covered by Ross is 6 miles and the time taken by him is: 2 hours.
This means that his speed is:
[tex]Speed=\dfrac{6\ miles}{2\ hours}\\\\i.e.\\\\Speed=2\ miles\ per\ hour[/tex]
Also,
[tex]Distance=Speed\times time[/tex]
Hence, distance covered by him in 4 hours at the same speed is:
[tex]Distance=3\times 4\\\\i.e.\\\\Distance=12\ miles[/tex]
and the distance traveled by him in 3 hours is:
[tex]Distance=3\times 3\\\\i.e.\\\\Distance=9\ miles[/tex]
Hence, the extra miles he covers in 1 hour is:
[tex]12-9=3\ miles[/tex]
