A bus takes 195 minutes to travel a distance of (2 x +30) km at an average speed of ( x-20) km/hr. calculate the actual distance travelled. Give your answer in kilometers.
Distance=Speed×Time
2x+30= (x-20)(195÷60)
2x+30=(x-20)×3.25
2x+30=3.25x - 65
2x-3.25x=-65-30
-1.25x=-95
x=76
Distance=2x+30
=(2×76)+30
=182km Ans.
