Two cars leave towns 510 kilometers apart at the same time and travel toward each other. One car's rate is 14 kilometers per hour less than the other's. If they meet in 3 hours, what is the rate of the slower car?
Do not do any rounding.

time = 3 hours

speed = distance / time

2x+18 = 510/3

2x+18= 170

2x= 170-18

2x= 152

x= 152 /2

x= 76 km/h

add 18 to x to find the speed of the other car

$4034.40

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
