Answer:

Speed of boat in still water is  14 km/hr and speed of current is 8 km/hr

Step-by-step explanation:

Average speed of down stream = 22 km/h

Average speed of up stream = 6 km/hr

Consider the speed of boat in still water be  x km/hr and speed of current be  y  km/hr

As such speed of down stream would be  x + y km/hr and speed of down stream would be  x - y km/hr. i.e

x+y = 22

x-y = 6

by solving these two equation, we get

2x=28

x=14 km/hr

y=16-13

y=8 km/hr

Hence, the speed of boat in still water is  14 km/hr and speed of current is 8 km/hr

Answer:

3.7hours

Step-by-step explanation:

Step one:

A car travels 360 miles in 8 hours

the speed is calculated as

speed= distance/time

speed= 360/8

speed= 45mph

Step two:

How much time will it take traveling 168 miles?

having found the speed, which is the rate at which the car is tavelling

time= distance/speed

time= 168/45

time= 3.7hours
