A person travelled by train for 1 hour at a speed of 50 km/hr. He then travelled by a taxi for 30 minutes at a speed of 32 km/hr to complete his journey. What is the average speed at which he travelled during the journey?
The formula to calculate average speed is, Average speed = Total distance / Total time distance travelled can be obtained by formula, distance = speed x time distance travelled by train = d1 = 50km/hr x 1hr = 50km distance travelled by taxi = d2 = 32km/hr x 0.5hr = 16km hence total distance travelled…
