Question

a car travels a distance of 85 km in 2 hrs at a speed of 50 kmph and partly at a speed of 25 kmph.the distance travelled at speed of 50kmph is

Answer 1

let the time taken for 50 kmph be x
then for 25 kmph it becomes (2-x)
now from question we have
50*x + 25*(2-x) = 85
25*x + 50 = 85
25*x = 35
x = 35/25
=> 7/5*60 = 42 mins for 50 kmph
