Two cars leave town at the same time and travel in opposite directions. Speed of car A is 12 km/h more than car B. They are 312km apart after 4 hours. Find the speed of each car.

Speed of car B is 33 km/h and speed of car A is

Step-by-step explanation:

Let speed of car B be km/h

Speed of car A is 12 km/h more than car B.

Therefore,

Speed of car A = km/h

Distance = Speed × Time

Distance travelled by car A in 4 hours = km = km

Distance travelled by car B in 4 hours = km

Also, cars A and B are 312km apart after 4 hours.

Speed of car B is 33 km/h and speed of car A is

c > -10.55

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
