Mr warren drove from Townsville to villaville at 70 mph and back again at a speed of 50 mph. His total driving time was 12 hours. How far apart are the two towns
Answers
Call the distance between the towns 'D' .
The time it takes to cover a distance is (distance) divided by (speed).
It takes Mr. Warren D/70 hours on the first trip, and it takes him D/50 hours on the return. All together, it takes him 12 hours.
D/70 + D/50 = 12 hours
Change the fractions to a common denominator (350) for adding: 5D / 350 + 7D / 350 = 12
Add: 12D / 350 = 12
Divide each side by 12 : D / 350 = 1
Multiply each side by 350 : D = 350 miles .
Check:
Going: 350mi / 70 mph = 5 hours
Coming: 350mi / 50 mph = 7 hours
Total 12 hours yay !
Warrendrove from Townsville à Villaville at 70 miles per hour and from Villaville to Townsville è 50 milesper hours He drove for a total of 12 hours. => 70 miles + 50 miles = 120 miles => 12 hours So the unit rate of his driving is 120 miles / 12 hours => 120 miles / 12 hours => 10 miles / hour thus, he drove in total for 10 miles per hour. And probably the 2 towns are about 60 miles away.
Kate made a box to hold her jewelry collection. She used 42 inches of wood to build the sides of the box. If the box was 9 Inches wide, how long was the box
Answers
We can use the 9 inches wide to determine that 18 inches of the 42 inches are the wide sides. 42 - 18 = 24, so we divide 24 by how many long sides there are, 2. 24 ÷ 2 = 12. The box was 12 inches long.
