It is given that the average speed of a subway train is 72 km/h.
At this average speed, how far does it travel in 12 minutes?

14.4km

Step-by-step explanation:

Average speed = distance/time

Given speed = 72km/h and

Time = 12minutes

Convert the time to hour

12mins = 12/60 = 0.2hour

Therefore

72 = distance/0.2

Cross multiply

Distance = 72 x 0.2

= 14.4km

It travels 14.4km in 12 mins

step-by-step explanation:

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
