The line plot above shows the distance students live (in miles) from the library. what is the difference in miles between the students who live closest and the furthest away?
a)
1
/2
b)
1
/8
c)
6
/8
d)
7
/8

Step-by-step explanation:

If they are travelling in opposite directions, their total distance is the 135.  So add their distances together to get 135

x=Quinn's speed

x+5 = James' speed

they each travel for 5 hours

speed x time = distance

x(5) + (x+5)(5) = 135

Quinn's distance + James' distance = total distance

5x+5x+25=135

10x = 110

x = 11

Quinn travels at 11 mph and James travels at 16 mph

Quinn travels 55 miles (5x11)

and James travels 80 miles (16 x 5)

80 + 55=135
