Cyclist A leaves point X at 12 noon and travels at constant velocity in a straight path. Cyclist B leaves point X at 2 p.m. trav
els the same path at constant velocity, and overtakes A at 4p.m. What was the speed of B? (1) Cyclist A weighs twice as much as Cyclist B.
(2) When Cyclist B overtook Cyclist A, both had traveled 75 miles.
The question might be trying to confuse the reader. Point (1) which states the difference in weight does not show any evidence on how it affects the speed of both cyclist. Point (2) show an important point where the distance traveled is 75 miles.
Cyclist B, who leave point X at 2pm overtook cyclist A at 4pm, showing that the time it took for B to overtook A is 2 hours
