A car runs 18 kilometers 5 / 2 hours, how many kilometers per hour?
18/2/5=18*5/2=45km
A car travels 48 kilometers in 4 / 5 hours. How many kilometers does the car travel in 1 hour? Process
48 / (4 / 5) = 48 * 5 / 4 = 60 km / h
How many hours does it take for a car to travel 297 km in 0.5 hours and 16.5 km?
1
16.5 △ 0.5 = 33 km
two
297 △ 33 = 9 hours
The distance of a train in 2 hours is 60 kilometers less than that of a car in 5 hours. The average distance of a train in an hour is 30 kilometers more than that of a car in an hour. How many kilometers Do trains and cars travel in each line in an hour
Don't just write x = what
Don't bring y
If the car travels x kilometers per hour, the train travels x + 30 kilometers per hour
5x-2(x+30)=60
5x-2x-60=60
3x=120
x=40
x+30=70
A: trains travel 70 kilometers per hour and cars 40 kilometers per hour
