Two cars traveling toward each other are 300 miles apart. Car A is traveling 10 miles per hour faster than car B. The cars pass after 5 hours. How fast is each car traveling?

Speed of car B = 25 miles/hr

Speed of car A = 35 miles/hr

Explanation:

Two cars meet at a distance = 300 miles

Let the speed of Car B = x miles/hr

Speed of car A = x + 10 miles/hr

Time when car passes, t = 5 hours

Speed of the cars = ?

So,

Distance of car A + Distance of car B = 300 miles

We know, distance = speed X time

So,

(x+10) 5 + 5x = 300

5x + 50 + 5x = 300

10x = 250

x = 25 miles/hr

Speed of car B = 25 miles/hr

Speed of car A = 25 + 10 = 35 miles/hr

Therefore,

Speed of car B = 25 miles/hr

Speed of car A = 35 miles/hr

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
