The distance from your house to your aunt's house is 228 miles you are twice as far from home as you are from your aunt's house How far have you traveled?

The ratio of the distances between me and my house, and me and my aunt's house is 2:1 ⇒ there are 2 + 1 = 3 parts to the distance between my house and my aunt's house ⇒ each part is worth the distance between the two houses divided by 3, that is 228 miles ÷ 3 = 76 miles ⇒ I am 2 parts from my house which is 2 x 76 miles = 152 miles & 1 part from my aunt's house which is 1 x 76 miles = 76 miles So if I am on my way to visit my aunt, I have travelled 152 miles from my house; Or if I am on my way home from visiting my aunt, I have travelled 76 miles from my aunt's house;


How much of a 100 miles trip completed in 3 hours was driven in the city if a truck drives at an average of 45 mph on the highway and 20 mph in the city?

time = distance/speedLet the distance driven in the city at 20 mph be c milesThen the distance driven on the highway is 100 - c milestime driven on highway + time driven in city = total time→ (100 - c) miles/45 mph + c miles/20 mph = 3 hours→ (4(100 - c) + 9c)/180 = 3→ 400 - 4c + 9c = 540→ 5c = 140→ c = 28Therefore the truck drove for 28 miles in the city.
