Help solve the following math problems (requiring formulas and answers) of synchronous refining and testing in six volumes of primary schools. Please a little faster. 10 minutes to help me answer. thank you 1. Solution: The distance from Siziwangqi to Beijing is1.5× 300000000 = 45000000 cm = 450 km.

So the fastest time is 450 km100 km/h = 4.5 hours.

2. Solution: First calculate the distance from Guangzhou to Dongguan, that is, 3× 2 million = 6 million cm.

On another picture, it is 6000000÷6= 1000000. So the scale of this map is 1: 1000000. .
