Question

The speed of a boat along the stream is 8 km/h and against the
stream is 6 km/hr. The time taken by the boat to sail 28 km in still
water is​

Answer 1

Answer:

given :

d = 28km

The speed of a boat along the stream is 8 km/h

and

The speed of a boat against the stream is 6 km/h

Step-by-step explanation:

here we have to take The speed of a boat against the stream is 6 km/h because it given in the question that the water Is still

now , by speed formula

note : first solve the formula

v = d / t

vt = d

t = d / v

now, by new formula

t = d/v

t = 28000/6 [it is given that 6 m/s then km will become m ]

t = 4,666 sec i.e 1.29 hours
