Question

a man covers a distance of 24 km in 3 whole 1 upon 2 hours partly on foot at the speed of 4.5 km per hour and the partly on bicycle at the speed of 10 km per hour find the distance covered on foot​

Answer 1

HEYA!??

Time =distance /speed

7/2=(x/4.5)+((24-x) /10)

7/2=2x/9+(24-x) /10

7/2=(20x+216-9x)/90

7=(11x+216)/45

315=11x+216

99=11x

x=9

distance covered by foot 9kms

HOPE IT WORKS!!
