Question from Athish, a student:

the driver of the car is travelling at 36 km/hr and spots a bus 80 m ahead of him after 1 hr the bus is 120 m behind the car what is the speed of the bus


Suppose the bus travels at $b$ km/hr then in 1 hour it will travel $b$ km. In this one hour the car travels $80 + 120 = 200$ m further than the bus travels. Convert the $200$ meters to kilometers and solve for $b.$
