Question

A car covers a distance of 350km with a speed of 60km/h and then covers a distance of 450km with a speed of 100km/h. calculate its average speed.​

Answer 1

Answer:

Step-by-step explanation:

s₁=350km

s₂=450km

v₁=60km/h

v₂=100km/h

Average Speed=[(s₁+s₂)v₁v₂]÷(s₁v₂+s₂v₁)

                          =[(350+450)100*60]÷(350*100+450*60)

                          =(800*6000)÷(35000+27000)

                          =4800000÷62000

                          =77.41km/h
