Answer:
67.1
Step-by-step explanation:
Given That:
Time = 200 minutes = 3.5 hours
Distance = 235 miles
We Know That:
Speed = Distance / Time
SO, Speed = 235 divided by 3.5 = 67.1428571
Round this 3sf = 67.1
Hope this helps.
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number
In this case a=5, and d=-2 so
a(n)=5-2(n-1) which can be simplified...
a(n)=5-2n+2
a(n)=7-2n
The domain is restricted to integers from 1 to +oo.
