There is another way to do this which is a little shorter. Note that the difference between 90 km/hr and 75 km/hr is 15 km/hr. So we ask ourselves how long it takes to cover that additional 0.1 km at the rate of 15 km/hr. That is t=d/r = 0.100/15 = 0.00667 hr. Voila!

a) (velocity component across)= (river width)/crossing time)= 2.0 km/hr b) If the boat's speed with respect to water is 2.5 km/h and the component across the river is 2.0 km/h, the downstream component must be 1.5 km/h (Consider the Pythagorean theorem). c) Since it travels at...

First, let's figure out how many km the ship travels in 1 hour. 84 / 3.5 = 24 km It travels 24 km in 1 hour. Next, divide: 1050 / 24 = 43.75 hours or 1 day and 19.75 hours. Another way to do this problem is to set up a proportion and cross multiply. 84 / 3.5 = 1050 / x 84x = ...
