If a car travels for a distance of 16 km at an average speed of 50 km/h and then for a distance of 52 km at an average speed of 80 km/h, what is the total time for the journey in minutes, to the nearest minute?

  • maths -

    (16/50+52/80)*60min
    =(0.32+0.65)*60 min
    =0.97*60 min
    =58.2 min
    =58 min. (to the nearest minute)
