Answer:
36 miles per hour
Step-by-step explanation:
Total distance = 70 + 110 = 180 miles
Total time = 2 + 3 = 5 hours
average speed
= total distance ÷ total time
= 180 ÷ 5
= 36 miles/hour
It will take you 2 hours since ur going 70 mph divide the 140 mph by 70mph . Hope this helps :)
Answer:
C
Step-by-step explanation:
the explicit formula for an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
from the recursive formula in the form
= + d
given
= - 7
with d = - 7 and a₁ = 4 , then explicit formula is
= 4 + (n - 1)(- 7)
