Ben and Jerry start from the same point and
ride their bicycles in opposite directions. If Ben rides twice
as fast as Jerry and they are 90 miles apart after four hours,
then what is the speed of each rider?
.
Let x = speed (mph) of Jerry
then
2x = speed of Ben
.
4x + 4(2x) = 90
4x + 8x = 90
12x = 90
x = 90/12
x = 7.5 mph (Jerry's speed)
.
Ben's speed:
2x = 2(7.5) = 15 mph
