Question

A bus travelled the first 60km Journey in one hour
and the next 80 km in the next one hour - Calculate the
average speed of the bus during the journey.​

Answer 1

Average speed = total distance/total time

60+80 = 140 km/hr

140/2 = 70 km per hr

Answer 2

Answer:

${\therefore \tt the \: average \: speed \: of \: the \: bus \: is \: 70 \: km/hr}$

explanation:

$\mathsf{average \: speed =\dfrac{total \: distance}{total \: time \: taken} }$

Total distance = 60 + 80 = 140 km

Total time = 1 + 1 = 2 hours

$\mathsf{average \: speed =\dfrac{140}{2} = 70 \: km/hr}$
