Answer:
Step-by-step explanation:
x + 0.7 = 1 - 0.2x
Add 0.2x to both sides
x + 0.2x + 0.7 = 1 - 0.2x + 0.2x
1.2x + 0.7 = 1
Subtract 0.7 from both sides:
1.2x + 0.7 - 0.7 = 1 - 0.7
1.2x = 0.3
Divide both sides by 1.2:
1.2x/1.2 = 0.3/1.2
x = 0.25
Answer:
24 kilometers
Step-by-step explanation:
1.2 kilometers per minute; 12 kilometers
Step-by-step explanation:
We know that 60 minutes makes 1 hour.
Therefore, to convert the speed to kilometers per minute, we simply divide 72 kilometers per hour by 60 minutes:
72 / 60 = 1.2 kilometers per minute.
Distance is given as speed multiplied by time.
Therefore, in 10 mins, the car travels:
1.2 * 20 = 24 kilometers.
