A ship traveled 12 miles per hour going East & then went at 18 miles per hour heading south total 156 miles in 10 hours. How many miles did it travel going East?

The distance travels in going east is 48 miles.

Step-by-step explanation:

Speed of ship while traveling in east = 12 miles/hour.

Speed of ship while travelling in south = 18 miles/hour.

The total distance covered by ship = 156 miles.

The total time taken by ship to cover 156 miles = 10 hours.

Let the distance traveled by ship in east = ' x ' miles.

So the distance covered by ship in south = ( 156 - x ) miles.

Let the time taken by ship to cover ' x ' miles in east is ' t ' hour.

So the time taken by ship to cover " 156 - x " miles = " 10 - t " hour.

We know the formula,

t + ( 10 - t ) = 10 hour.

 = 10

x + 312 = 360

x = 48 miles.

So the distance travels in going east is 48 miles.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
