Distance = speed × Time. ⇒ 60 × (20/60) ⇒ 60 × (1/3) ⇒ 20 km . Total Distance= 20 + 20 = 40 km. Total time = 40 + 20 = 60 minutes = 1 hour. Now, average speed. Average speed = total distance/total time. ⇒ 40 km/hr. ∴The average speed is 40 km/hr. Alternate Method. Difference between speed 30 km/hr. The ratio of time 2 : 1. The
Speed = Distance/Time. Now, according to the question, the car has traveled 30 km in three-quarters of an hour. Total time taken by the car = (15 + 15 + 15) min = 45/60 hour = 3/4 hour. So, the average speed of the car = Total distance/Total time. = 30 3 4 = 10 × 4 = 40 k m h.
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? Here’s the best way to solve it.
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 moves with a speed of 40 km per hour for 15 minutes and then with a speed of 60 km per hour for the next 15 minute calculate the total distance - 7169412 krishnanhoneydew krishnanhoneydew 18.12.2018
A car travels a distance of 200 km along a straight road at a speed of 40 km/h. The car returns back to same location with a speed of 60 km/h. Find the average speed and the average velocity of the car for the entire journey.

A car makes a 200-km trip at an average speed of 40 km/h. A second car starting 1.0 h later arrives at their mutual destination at the same time. What was the average speed of the second car? [Hint: For a car under constant velocity, xr=Xi + vt.]
If you travel at a speed of 40 kilometers per hour for a certain amount of time, how far will you travel? Compute the distance in miles, kilometers, feet, and meters.
