Question

a car at a speed of 40km/h takes 2hrs then the traveller takes a break of 60 mins and then drives at a speed of 60km/h in 3hrs find average speed​

Answer 1

Answer:

43.33kmph

Explanation:

Avergare speed is defined as the ratio of the total distance covered by total time taken.

Here,

$total \: time = (2 + \frac{60min}{60min} + 3)hr \: = 6hrs$

$total \: dist. = 40kmph \times 2h + 60kmph \times 3h = 80km + 180km = 260 \: km$

So, average speed is

$s = \frac{260km}{6h} = 43.33kmph$
