Refer to the diagram shown below.
Let the distance that Sassoon travels is d miles.
Let his average speed be x mph.
The time of travel is from 1 p.m. to 4 p.m., which is 3 hours.
Therefore
3x = d (1)
The distance that Archer travels is (d + 300) miles.
The time of travel is from 9 a.m. to 4 p.m., which is 7 hours.
The average traveling speed is (x + 20) mph, therefore
7(x + 20) = d + 300
That is,
7x + 140 = d + 300
7x = d + 160 (2)
Subtract (1) from (2).
7x - 3x = d + 160 - d
4x = 160
x = 40 mph (Sassoon's average speed)
x+20 = 60 mph (Archer's average speed)
From (1), obtain d = 120 mi
Answer:
Archer's speed is 60 mph.
Sassoon's speed is 40 mph.

Answer:
x=
13
/14
Step-by-step explanation:
Let's solve your equation step-by-step.
5x−5
x−2
=
1
3
Step 1: Cross-multiply.
5x−5
x−2
=
1
3
(5x−5)*(3)=1*(x−2)
15x−15=x−2
Step 2: Subtract x from both sides.
15x−15−x=x−2−x
14x−15=−2
Step 3: Add 15 to both sides.
14x−15+15=−2+15
14x=13
Step 4: Divide both sides by 14.
14x
14
=
13

x=
