Question

pls tell tomorrow it is urgent.

The speed of boat in still water is 13 kilometre per hour if the boat travels 84.7 kilometre downstream in 5.5 hours find the speed of stream

Answer 1

Answer:

2.4 km/hr

Step-by-step explanation:

Let speed of stream be xkm/hr

Then speed of boat downstream will be (x+13)km/hr

Distance travelled downstream = 84.7 km

Time taken = 5.5 hours

So, 13+x = 84.7/5.5 (Time= Distance / speed)

13+x = 15.4

x = 2.4

So speed of stream will be 2.4 km/hr
