Answer:
REPRESENT THE USUAL SPEED AS x And then form a Quadratic explaination .
Step-by-step explanation:
Let the usual speed be x kmph
Now the time taken to cover 1500 = 1500/x [ Since time = Distance / Speed ]
time taken to cover 1500 km when speed is speed is increased by 100 km per hour = 1500/x +100
A.T.Q ......
1500/x + 1/2 = 1500/x+100 And do the further evaluation . ☺ Sorry but I couldn't do much cuz I was busy !
