Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(2,5)...x1 = 2 and y1 = 5
(9,8)...x2 = 9 and y2 = 8
now we sub
d = sqrt ((9 - 2)^2 + (8 - 5)^2)
d = sqrt ((7^2) + (3^2))
d = sqrt (49 + 9)
d = sqrt 58 <===

Answer:

George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus

Step-by-step explanation:

The question is

Find how many kilometers they traveled by bike

Let

x ----> kilometers traveled by bike

y ----> kilometers traveled by bus

we know that

They traveled 300 kilometers in total

$x+y=300$ ----> equation A

They biked 70 kilometers more than they were bus

$x=y+70$ ----> equation B

substitute equation B in equation A

$(y+70)+y=300$

solve for y

$2y+70=300\\2y=300-70\\2y=230\\y=115$

Find the value of x

$x=115+70=185$

therefore

George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus
