29.3 mph because the first bicyclist went 88 miles while the second went only 84 at 28 mph
-10 = -3x - 82
3x = -82 + 10
3x = -72
x = -24
hope it helps
Answer:
Step-by-step explanation:
The given ordered pair is (2,162)(3,486).
Let the equation be
when x=2, y=162
This gives:
Also when x=3, y=486,
Divide the second equation by the first,
When b=3, we have
The exponential equation is:
To cover 5 miles the wheel covers 3771.42 (approx) turns.
Step-by-step explanation:
Given,
In 20 times turns wheel covers 140 feet.
1 mile = 5280 feet
To find the number of times wheels turns to cover 5 miles.
We will apply unitary method.
Now,
5 miles = 5×5280 feet = 26400 feet
140 feet covers in 20 turns
1 feet covers turns
26400 feet covers in ×26400 turns
= 3771.42 (approx) turns
