Map scale 1: 1500000. the segment on the map with a length of 25.6 cm corresponds to the distance that the car covered in 5 hours and 20 minutes. find the speed of the car.

To solve this problem, remember that the scale shows: how many times each line. plotted on the map, reduced in relation to its actual dimensions on the ground. Therefore, a scale of 1: 1,500,000 means that 1cm on the map corresponds to 1,500,000 cm on the ground. Let’s find the distance on the terrain of a segment of 25.6 cm.

25.6 * 1,500,000 = 38,400,000 cm = 384 kilometers.

Distance is equal to the product of time and speed. s = v * t, where s is distance, v is speed, t is time. Let’s calculate the speed.

v = 384/320 = 1.2 km / min.

Answer: 1.2 km / min.
