Q439: A person travels from A to B at a speed of 40 kmph and returns by increasing his speed by 50%. What is his average speed for both the trips?

46.67 km/h

48 km/h

45 km/h

50 km/h

Explanation

Given:

Speed from A to B = 40 km/h
Speed from B to A = 40 km/h + 50% of 40 km/h = 40 + 20 = 60 km/h

Find:

Average speed for the whole journey (both ways).

Formula for average speed when distance is the same but speeds differ:

text{Average speed} = frac{2 times text{Speed}_1 times text{Speed}_2}{text{Speed}_1 + text{Speed}_2}

Plug in values:

= frac{2 times 40 times 60}{40 + 60} = frac{4800}{100} = 48 text{ km/h}

$= 4800$

$= 48 km/h$
