Question

Two buses leave a station at the same time and travel in opposite directions. One bus travels 17 slower than the other. If the two buses are 230 miles apart after 2 hours, what is the rate of each bus

Answer 1

230 = 2B + 2(B-17) = 4B-34

4B = 264

B = 66 mph

B-17 = 49 mph

in 2 hours one bus goes 2(66) = 132

in 2 hours the other bus goes 2(49)= 98

132+98 = 230 miles
