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?

Text Solution

Verified by Experts

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`
