Question

Helen drivers 10km/h faster than Maggie Helen drivers 200 km in the same time that Maggie drivers 150 km find there driving speed​

Answer 1

Answer:

Step-by-step explanation:

LET SPEED OF MAGGIE BE X

THEREFORE SPEED OF HELEN = X+10

TIME TAKEN BY HELEN TO TRAVEL 200 KM = T (SAY)= DISTANCE/SPEED=200/X+10

TIME TAKEN BY MAGIEN TO TRAVE 150KM = T(SAY)= DISTANCE/SPEED = 150/X

SINCE T ON LHS ARE EQUAL THERFORE RHS ARE EQUAL

200/X+10= 150/X

200X = 1500 + 150X

50X = 1500

X= 30 KM/HR

X+10 = 40 KM/HR

HENCE SPEED OF MAGGIE IS 30 AND OF HELEN IS 40
