Question

Kiara hired a taxi and noted the initial reading of its odometer as 24803 km. After the
journey, she noted the final reading of the odometer as 25118 km. If the journey took 4
hours 40 minutes, calculate the average speed of the taxi during the entire journey.

Answer 1

Explanation:

initial reading =24803km

reading after journey=25118km

distance travel=final reading-initial reading

=25118km-24803km=315km

time=4hrs 40 min=280min

average speed=

$\frac{total \: distance}{total \: time} = \frac{315km}{280min} = 1.125km |min$

in hrs =

$1.125km \div \frac{1}{60} \\ = 1.125 \times 60 = 67.5$

so 67.5km/hr is the average speed
