Answer 1

Вот просто и понятно. 

Answer 2

144км-144000м
144000:1200=120
36км-36000м
36000:1200=30
8км-8000м
8000:1200=6 800/1200=6 8/12=6 2/3
54км-54000м
54000:1200=45

Answer 3

Calculating the Distance Traveled by the Car

To calculate the distance the car will travel in a certain amount of time, we can use the formula:

distance = speed × time

Given that the speed of the car is 1200 meters per minute, we can use this formula to find the distance traveled in different time intervals.

Calculations

a) For 144 km: - We first convert the speed from meters per minute to kilometers per hour: - 1200 meters/minute = 1200 × 60 meters/hour = 72000 meters/hour - 72000 meters/hour = 72 kilometers/hour - Now, we can calculate the time it takes to travel 144 kilometers: - time = distance / speed - time = 144 km / 72 km/h = 2 hours

b) For 36 km: - Using the same formula: - time = 36 km / 72 km/h = 0.5 hours

c) For 8 km: - Using the same formula: - time = 8 km / 72 km/h = 0.111 hours

d) For 54 km: - Using the same formula: - time = 54 km / 72 km/h = 0.75 hours

Conclusion

Based on the given speed of 1200 meters per minute, the car will travel: - a) 144 km in 2 hours - b) 36 km in 0.5 hours - c) 8 km in 0.111 hours - d) 54 km in 0.75 hours
