WebThe distance travelled by both is 30 km. Therefore, the equation to be solved is: 3r + 3(r + 2) = 30 3r + 3r + 6 = 30 − 6 −6 6r 6 = 24 6 r = 4 km/h 3 r + 3 ( r + 2) = 30 3 r + 3 r + 6 = 30 − 6 − 6 6 r 6 = 24 6 r = 4 km/h This means that Natasha walks at 4 km/h and Joey walks at 6 km/h. Example 8.8.2 WebCorrect option is A) Let the distance be=d Speed of boat in upstream =5−1=4 km/h Speed of the boat in downstream=5+1=6 km/h According to the question, 4d− 6d=3 123d−2d=3 d=36 km Was this answer helpful? 0 0 Similar questions Medium View solution > A man can row the boat at 5 km/hr in still water.
Calculating average speed and velocity edited - Khan Academy
Web4.16 kilometers = 2.585 miles. Formula: multiply the value in kilometers by the conversion factor '0.62137119223798'. So, 4.16 kilometers = 4.16 × 0.62137119223798 = 2.58490415971 miles.

WebHere is an explanation why: if you were to take both cars of type A and want to cover 100 kilometers with each of them, you would need not 200 / 2.5 = 80 liters, but 125 liters of petrol (100 liters for the first car and 25 liters for the second). The French will get it right by multiplying 200 x 0.625 = 125. WebLet x be the speed of the truck.Since they are travelling in the opposite direction, the relative speed will be 54 + x. 1 = 80 / (54 + x) 54 + x = 80. x = 80 - 54. x = 26. Hence the speed of the truck is 26 km/hr. Example 2 : A backpacker was walking at a speed of 5 km/hr towards Mississauga that was 40 km away. Web1) Allow 1 hour for every 3 miles walked (equivalent to 4.83 kilometers) 2) Add 1 hour for every 2000 feet climbed (equivalent to 1 minute for every 10 metres) There have been as many attempts to "improve" this basic rule as grains of sand. For a start, Naismith was a very fit mountineer and not everyove walks at 4.83 kph. how to screen on windows
