Let time is t
since they both went in opposite directions then the distance between them is the sum of the distance between each of them and the origin point
49t + 56t =420 is the equation
to solve: 105t = 420 , t = 4 hours
Answer:
60 km
Step-by-step explanation:
the line is constant around 3
assuming the scale is by 1,
a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4
b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1
c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1
