Answer:
d = 711 miles
Step-by-step explanation:
The speed s of the car is given by :
...(1)
Where
d is the stopping distance
We need to find the stopping distance of a car travelling at 80 mph.
Rearranging equation (1) for d.
![s^2=9d\\\\d=\dfrac{s^2}{9}\\\\d=\dfrac{80^2}{9}\\\\d=711.1\ miles](https://tex.z-dn.net/?f=s%5E2%3D9d%5C%5C%5C%5Cd%3D%5Cdfrac%7Bs%5E2%7D%7B9%7D%5C%5C%5C%5Cd%3D%5Cdfrac%7B80%5E2%7D%7B9%7D%5C%5C%5C%5Cd%3D711.1%5C%20miles)
or
d = 711 miles
So, the required stopping distance is 711 miles.
Answer:
Dot bikes 7m+10 miles this week.
Step-by-step explanation:
Distance of one loop = m miles
Distance of 2 loops = 2m
Distance of 3 loops = 3m
Distance covered on Sunday = 10 miles
Total distance = Monday + Wednesday + Friday + Sunday
Total distance = 2 loops + 2 loops + 3 loops + 10 miles
Total distance = 2m + 2m + 3m + 10
Total distance = (7m+10) miles
Dot bikes 7m+10 miles this week.
