sam left his school 305 he walked speed 32 mph 15 minutes later al started running

### Walking 5/6 of his usual speed, a man is 10 minute too late. The usual time taken by him to cover that distance is:

he is walking 5/6 th of his speed, i.e

Actual speed : present speed = 6 : 5

as we know speed = distance/Time

so the Time should be = 5 : 6

so , Let actual time taken is 5x

present time taken is 6x

so, 6x-5x =10

=> x=10

=>5x= 50

So the actual ime taken is 50 mins .

*Relative*pace

*If two bodies are *moving* (*within the* *same* *path* or *in the* *wrong way*), then the *speed* *of one* *physique* with *regard* *towards the* other *is known as* its relative *pace*.*

*Relative *speed* *is a* phenomenon that we *observe* *everyday*. Suppose *you are* travelling in *school* bus *and there’s a* *2nd* bus coming *in the* *opposite direction*, then *it seems that* *the second* Bus is *moving* *much faster* than *actual*. If *both* the Buses *had been* *moving* *within the* *exact same* *path* at *exact same* speeds, *they seem* *to be* stationary if *seen* from *one* *of those* Busses, *although* *they may* *really* be *in a* *speed* of *100* km/hr *every*. *What exactly* *you really* *notice* is your *speed* relative *towards the* other. *
