A log boat travels about 5.5 km in one hour. How long will it take to go to a distance of 10 km?

Distance =5.5 km , Time =1 hrs

Speed =(Distance/Time) = (5.5/1) =5.5 km/hrs

Now , Distance=10km

Time =(Distance/speed)=10/5.5 =1.81 hrs

How long will it take a boat to travel 60 km at a speed of 35 km an hour?

From the wording of the question,

60 km has one significant figure of precision.

We are talking scalars here and not vectors. Assume one, constant direction.

The speed is NET and no other speeds need be considered.

Therefore v = d/t or t = d/v

t = 60km / (35km/hr) = 2 hours

Greater precision in answer would require greater precision in the initial measurements.

A motorboat in still water travels at a speed of 48 km/hr. It goes 64 km upstream in 1 hour. What will be the time taken by it to cover the same distance down the stream?

We are given that a motor boat travels at 48 km/h. We are also given that the same motor boat travels 64 km in one hour upstream, ie the speed of the boat up the stream is even more than its speed in still water, whereas it is required to be less than the speed of the motorboat in still water.

Let the speed of boat and current be x km/h and y km/hr respectively

Upstream speed = (x - y) km/h

Downstream speed = (x + y) km/h

As we know,

Speed = Distance/Time

Condition first x – y = 4/2

x – y = 2 ---(1)

Condition second x + y = 4/(1/3)

x + y = 12 ---(2)

From equation (1) and equation (2)

x = 7 and y = 5

Require time to cover 21/2 km in still water = (21/2)/7 = 21/(2 × 7) =

112 hours

**Short trick:**

Upstream speed = 12 km/hr and Downstream speed = 2 km/hr, then

Speed of boat = (12 + 2)/2 = 7 km/hr

Require time to cover 21/2 km in still water = (21/2)/7 = 21/(2 × 7) =

112 hours
