Time x rate = distance 1: It took a woman 3 minutes to ride from P village to Q village at a speed of 24 km/h, and it is known that the distance from P village to Q village on the map is 8cm. Find the scale of the map. 3 minutes = 3/60h = 1/20h, so the completed Ppq = 1/20h, 24km/h = 24/20 = 6/5km =1.2km, converted into units of the same size. Even if the unit is converted into the same unit, you don't need to write it)1.2km =1200m =120000m = > actual PQ 8cm => map PQ scale = 8:120000 =1:. (a) Find out the actual distance between cities A and B. You can directly calculate the actual distance xkm 2cm:5cm = 9km:xkm with equal proportion. Go to the unit 2:5 = 9:x 2x = 45 x = 22.5(km) or change it to1:9km = 9000m2cm: 9000m =1cm: 4500m. 5cm = & gt4.5km x 5 = 22.5km (b) If it takes 50 minutes for Jinbao to ride from City A to City B, ask for his speed. (The answer is expressed in km/h .. h is the answer, so the speed of turning 50m = 5/6h = distance/hour = 22.5 ÷ (5/6) = 45/2 x 6/5 = 27 (km/h).

1.the distance from p village to q village = 24 * (3/24) *100000 = 300000 cm.

The scale of the map = 300,000: 3 =100,000: 1.2(a). The actual distance between the two cities, A and B = 900,000 * 5/2 = 2,250,000 cm = 22.5 km (b). His speed = 22.5/(52. = 27 mins 20 1 3-09-1616: 02: 05 supplement: correction:1. Distance from village P to village Q = 24 * (3/60) * 100000 = 65430.

Map scale = 8:120000 =1:15000 (b). Its speed = 22.5/(50/60) = 27 km/h.
