The distance between 2 cities is 145 miles . A truck can cover this distance in 2.5 hours. A car is a.5 times as fast as the moving truck. How long does it take to meet, if they start moving simotanously

25 minutes

Step-by-step explanation:

Given that:

Distance between 2 cities = 145 miles

Time taken by truck = 2. 5 hours

Speed of car = 5 times the speed of truck

Speed of truck = distance / time

Speed of truck = 145 / 2.5

Speed of truck = 58 mph

Speed of car = 5 * 58 = 290 miles per hour

Time it takes to meet :

Time taken = distance / combined speed

Time taken = 145 / (290 + 58)

Time taken = 145 / 348

Time taken = 0.4166666 hours

Time taken = 0.4166666 * 60 = 25 minutes

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
