Lydia's speed on Tuesday was 180 miles divided by 3 hours, or 60 mph. If she then drove 7 hours at 60 mph, she drove 420 miles. Altogether, she drove 420 + 180 or 600 miles.

40 mph

About 8.3 mph at that rate of travel.

1.7 or 1.8 hours

Divide 6 into 330 to figure MPH

505 miles in 7 hours has a value of about

44 mph

36 mph

200 miles each way.

Average seed = (total distance) / (total time) = (80+100) / (2+3) = 180/5 = 36 miles per hour

100 miles

416 miles

9

36 mph. (80+100) / (2+3) = 36

180 miles, 5 hours; 36 mph

36 mph

60 x 4 = 240 miles.

Distance = rate * time 600 miles = rate * 12 hours rate of speed = on average, 50 miler per hour

36 miles per hour

To calculate the average speed you divide the distance by the time.

a unit rate is a mathematical term refering to how much or how many to a unit of 1. that was kind of confusing so let me give you an example. if you drove a total of 55 miles in 2 hours. the unit rate would be how many miles you drove in 1 hour, or 1 minute depending on the question.EXP: your on vacation and your family drove 55 miles in to hours. how many miles did you drive in 1 hour.55 divided by 2 = 27.52 divided by 2 = 1 unit rate = 27.5 over 1divide by the denominator

The most important formula to memorize is: Distance = Rate (speed) x Time (hours or minutes, etc..) Therefore, the average rate on the first date can be calculated as follows: Rate = Distance / Speed 348 miles divided by 6 hours = 58 miles per hour. At that rate, a total of 58 miles times 9 hour = 522 miles can be driven by the family in the next 9 hours.

180 miles / 5 hours = 36 miles per hour (average)

Dividing distance travelled by time taken gives 440/8 = 55 miles per hour.

During the first hour, they covered (60 x 1) = 60 miles.During the next 2 hours, they covered (45 x 2) = 90 miles.The total distance covered was (60 + 90) = 150 miles.The average rate was (distance/time) = (150/3) = 50 miles per hour.
