Two cars leave town at the same time in opposite directions. One travels 35 km/h and the other 40 km/h. In how many hours will they be 200 km apart? The cars are separating at a rate of 35+40 = 75 km/h Equation: time = distance/rate Ans: time = 200km/75km/h = (200/75)hr = 2 2/3 hrs = 2hr 40min-----2. Two cars leave town at the same time in the A car travels 30km with a speed of 60km/h and next 30km with uniform speed 40 km/ h calculate 1. The total time 2. The av.speed 3. 75 min 4. 48 km/ h SOLUTION: A car travels at 40 km/h for 30 min and 60 km/h for 15 min. How far does it travel in this time? Algebra -> Customizable Word Problem Solvers -> Travel -> SOLUTION: A car travels at 40 km/h for 30 min and 60 km/h for 15 min. The time is taken to cover the distance of 40 k m with an average speed of 40 k m h-1 ⇒ t 2 = d i s tan c e t r a v e l l e d a v e r a g e s p e e d On putting the given data in the above equation we get, In other words, we will calculate the time it takes to drive 40 kilometers at 60 kilometers per hour. We will show you in detail how to get the answer in hours, minutes and seconds. First, we calculate total hours by dividing 40 km by 60 kmh. The total hours will be the whole number to the left of the decimal point. 40 km ÷ 60 kmh = 0.66666667 If half of the total time it travels with speed 80 k m / h and in rest half time its speed becomes 40 k m / h, the average speed of car will be: Q. A car travels half of the distance with constant velocity 40 km/h and another half with a constant velocity of 60 km/h along a straight line. A car travels 40 kilometers at an average speed of 80 km/hr and then travels another40 kilometers at a speed of 40 km/hr. The average speed for the trip is a) 40km/hr b) 45km/hr c) 48 km/hr d) 53 km/hr e) 73 km/hr The inverse of the conversion factor is that 1 mile per hour is equal to 0.0402336 times 40 kilometers per hour. It can also be expressed as: 40 kilometers per hour is equal to 1 0.0402336 miles per hour. .
