Arithmetic Mcqs

Q.  A person travels from x to y at a speed of 40Km/h and returns by increasing his speed 50%. What is his average speed for both the trips?

a. 36km/h
b. 45km/h
c. 48km/h
d. 50km/h


ANSWER: See Answer
 
Speed of person from x to y =40 km/h

Speed of person from y to x =(40×150)/100 = 60km/h

Since the distance travelled is same

Therefore, Average Speed = (2x40x60)/40+60 = 48km/h
