Answer:
Speed of car A = 40 mph
Speed of car B = 50 mph
Step-by-step explanation:
Given:
Distance travelled by car A = 120 miles
Distance travelled by car B = 120 miles
To Find:
speed of each car = ?
Solution:
Let the speed of car A be x
then speed of car B is (x +10)
The Time taken for each car is same
Time taken for car A = Time taken for car B
We know that time = 
Time taken for car A
=>
---------------------------(1)
Similarly
Time taken for car B
=>
-----------------------(2)
Equating (1) and (2), we get
= 

120x + 1200 = 150x
1200 = 150x-120 x
1200 = 30x

x= 40
Speed of car A = 40mph
Speed of car B = (x+10) = (x+40) = 50mph
According to a daylight calculator for Fairbanks, AK, sun rises at 07:40 and sun sets at 20:12, giving 12 hours and 32 minutes of daylight.
Note that it is not a mistake that daylight is not exactly 12 hours on that day due to refraction of the sun's rays at sunrise and sunset.
At Fairbanks, near equality to 12 hours occurs on March 16 with sunrise at 07:58 and sunset at 19:57.
When writing equivalent expressions, there are often several possible orders in which to simplify them. However, they will all take you to the same result as long as you do not make a mistake when using the properties. In this example, you will distribute the outer exponent first using the Power of a Product Property.

Answer: " m∠SRW = 95 ° " .
________________________________________________
Since m∠TRV = 95° ;
and: ∠TRV and ∠SRW are vertical angles;
and: we are given: " m∠TRV = 95° " ;
and: vertical angles are congruent;
So, m∠TRV = m∠SRW = 95° .
