Speed of truck is r.
__________________speed_____________time____________distance
Bus_______________r-15______________(___)___________190
Truck_____________r_________________(___)___________135
We need time expressions for the equal time of both bus and truck:
__________________speed_____________time____________distance
Bus_______________r-15______________190/(r-15)___________190
Truck_____________r_________________135/r___________135
You should already sense a mistake in the given information. Equal time, the bus is slower but traveled more miles than the truck. This cannot be. You mixed-up some information.
LCD r(r-15)

Why should we allow ?
