What you've posted is actually a rational equation.
What did you get when you solved this equation?
Please be complete. Thank you!
on a journey of 250 km, a driver calculated that by increasing his average speed, by 5 km/h, he would take 25 minutes less. find his usual average speed , correct to 2 dec. places.
Ans: 52.33 km/h
i really need to know how to get this answer- i've tried by forming the quadratic equation:
250 - 250 = 25
x (x+5) 60
by keeping the speed as x.
