Question

average speed of a car from A to B is 40 km per hour when its return to starting point then its average speed is 60 km per hour calculate its total average speed ​

Answer 1

Explanation:

speed of a car from A to B = x = 40km/hr

speed of a car from B to A = y = 60km/hr

Average speed of a car = 2xy/x+y

= (2 × 40 × 60)/40+60

= (2 × 40 × 60)/100

= 48 km/hr

Average speed of a car = 48km/hr

Answer 2

Answer:

50 km

Average = Sum of numbers/Numbers

Average = 40+60km/2. {'2' because there are two numbers, 40 and 60}

Average = 100km/2

Average = 50km
