2.5 km per hour
To do 56 miles in 3 hours and 30 minutes you must travel 16 miles per hour.
To solve this we must first assume that her rate of pay was constant through both of these days. (If she worked any overtime, than she might make more money during her overtime hours. If this is the case, there is not sufficient information to solve this problem.The next step is to calculate how many hours she worked in total. 9 + 7 = 16 hours.Then, we divide the amount of money earned by the number of hours worked. $116 / 16 = $7.25 per hour.
An easy way to remember how to do these is to think about the units:Speed = kilometers / hourNow plug in the values you know:Speed = 1.2 km / .1 hourSpeed = 12 km/hour
The speed in km/hour must be given. The answer is obtained by dividing 250 km by speed in km/hour
This question does not make sense--it is like asking "how many hours are in ten seconds?" Kilometers is a measurement of distances and hours of time, you must be measuring the same thing to convert units.
330 kilometers / 4.25 hours = 77.65 kilometers per hour

You must get yourself a watch that is graduated in kilometres.
Distance = Velocity times Time (d=vt)The distance that the person traveling at 73 km/h traveled is 73*2 which is 146 kilometers. The person driving at 84 km/h must travel at least 146+8, or 154 kilometers: 154 = (84)*t(t in the equation above is time). Divide both sides by 84, and t = 1+5/6 hours.5/6 of an hour is 50 minutes, so the per soon traveling at 84 kilometers per hour must travel for at least 1 hour and 50 minutes.
448 metres per hour climbing.
A breech must be reported within one hour.
256/8=32 she must work 32 hours.
2.5 km per hour
Exactly 1.7 kilometers per hour.Use the formula: d=rtwhere d is the distance you have to traveland r is the rate or speed you travel in (in this case is the kilometers per hour)and t is the time is takes to travel the distanceThus the equation would be: 85 = r × 50to find r, you must divide both sides by 5085 ÷ 50 = 1.7Therefore r=1.7you will have to travel at the speed of 1.7 kilometers per hour
