Question

a group of tourists walked s km down the main street of a town at a speed of v km/hr. then, they walked twice that distance down a side road. how much time t (in hours) did the tourists spend walking if it is known that they walked 2 km/hr slower on the side road than they did on the main road? find t when s

Answer 1

Total time in walking =s/v + 2s/(v-2)= s(3v-2)/((v)(v-2))

Step-by-step explanation:

In this problem we will be using a simple formula , which is -

speed =distance/ time

Time spent in walking down the main street =s/v hours

Speed while walking on the side road = v-2 km/hr

Distance walked on the side road = 2s km

Time taken to walk on the side road = 2s/(v-2)

Total time taken in walking = s/v + 2s/(v-2)= s(3v-2)/((v)(v-2))
