A person travelled a distance of 50 km in 8h. He covered a part of the distance on foot at the rate of 4 km/h and a part on a bicycle at the rate of 10 km/h . How much distance did he travel on foot? |
Answer» Total distance covered ` = 50km` Total time taken ` = 8` hours Let distance travelled by him by foot is `x` km and distance travelled by him on bicycle is `50-x` km. Then,`x/4+(50-x)/10 = 8` `=>5x+2(50-x) = 160` `=>5x+100-2x = 160` `=>3x = 60` `=> x = 20` So, distance travelled by him by foot is `20` km. |
