27 divided by 9 = 3 hours
3475 km / 5 hr = 695 km/h
She travelled 140 + 300 ie 440 km in 7 hours. Her average speed was 440/7 or just a hair under 63 kph.
Distance = Rate * Time or, for our purposes a little algebraic manipulation Rate = Distance/Time Rate = 200 km/5 hours = 40 kilometers per hour -----------------------------------
The average rate during those 4 hours is 83.5 km per hour.
The rate is 609 kilometers per 7 hours. The unit rate is 609/7 = 87 kilometers per hour.
280 kilometers / 4 hours = 280/4 kilometers per hour = 70 kilometers per hour
30 hours
Distance travelled = 120 kilometersGiven:Rate = 60kphtime = 2 hoursFind: DistanceDistance = Rate * Time= 60 km/hour * 2 hours= 120 km
27 divided by 9 = 3 hours
300 kilometers in 3 hours = 300/3 = 100 kilometers per hour
3475 km / 5 hr = 695 km/h
She travelled 140 + 300 ie 440 km in 7 hours. Her average speed was 440/7 or just a hair under 63 kph.
Distance = Rate * TimeAlgebraically manipulated,Time = Distance/RateTime = 4700 kilometers/190 kilometers per hour= 24.7 hours=============================
about 10 mph
Distance = Rate * Time or, for our purposes a little algebraic manipulation Rate = Distance/Time Rate = 200 km/5 hours = 40 kilometers per hour -----------------------------------
That's approximately 380 miles , so at 60 miles per hour , just over 6 hours ( or at 100 kilometers per hour , just over 6 hours ) Time equals Distance divided by Rate. You will have to use an average for Rate since stops, starts, and slow downs will occur.
