Quick help can’t my head round this ?
Two model cars, A and B are in a race
They start together on the starting line
Assume each car travels at a constant speed
Car A takes 30 seconds to complete each lap of the track
CarB takes a whole number of seconds to complete each lap of the track
Two cars next cross the starting line together 150 seconds after the start of the trade
Find the four possible times that car b could take to complete one lap

Car B's time to complete a lap could be 150 seconds, but it could also be some divisor of 150 that is NOT a multiple of 30. It could be 75 or 50 or 25.
Answer: 25s, 50s, 75s, 150s
