Answer:
0.9kmh (Not rounded) Per Minute of travel, and 18kmh (Not rounded) Per 20 Minutes
Explanation:
To find the rate of travel per minute, we first must divide 54KMH by 60KMH. We choose 60KMH as the divisor because you travel one KM per hour at this rate.
60 ÷ 54 = 0.9 so the car travels 0.9KM per hour at 54KMH
0.9 x 20 = 18 so the car travels 18KM in 20 minutes at 54KMH
