Question

car moves half of the time with velocity 80 km/h and half of the time 40 km/h to reach 60 km destination, how much time it will take to reach the destinatiom

Answer 1

let total time be x
according to question half time it covers distance= x/2*80=40x km
and other half time it covers distance=x/2*40=20x km
therefore 60x = 60 or x= 1 hour
