Question

A school bus travells at speed of 48 km/ h reaches from stop to school in 45 min. What is the distance of the schiol from stop

Answer 1

Answer:

36km

Step-by-step explanation:

As the time decreases,the distance covered also decreases

therefore this is a direct variation

here D=distance covered and T=time

since the speed is 48kmph it will cover 48km in 1 hour i.e 60 minutes

therefore

D∝T

48∝60

48=k×60 (k=constant of proportionality)

48=60k

48/60=k

0.6=k

now the time required to travel from school to stop is 45 minutes

now taking T=45 minutes

D∝T

D=kT

D=0.8×45

D=36km

therefore the distance between school and stop is 36km
