Question

a car travels 60 km in 2 hours and 40 km in 1 hour then average speed​

Answer 1

Step-by-step explanation:

Total distance = (60 + 40) = 100 km

Total time taken = (2 + 1) = 3 hours

Average speed = 100/3 kmph

Answer) The average speed of the car is 100/3 kmph.

Answer 2

A car travels (1)

Distance = 60 km

Time = 2 hrs

And

A car travels (2)

Distance = 40km

Time = 1 hr

We know Average speed

$= \frac{total \: distnce \: travelled}{total \: time \:taken }$

Total distance = Distance (1)+ Distance (2)

Total distance = (60+40) km

= 100km

Total time = Time (1)+Time (2)

Total Time = (2+1) hr

= 3hr

Average speed =

$= \frac{total \: distnce \: travelled}{total \: time \:taken }$

${\sf{\red{Put~the~values}}}$

$= \frac{100}{3}$

$= 33.33$
