the area of 4 walls and ceiling of a room is 107 metre per square. if the room is 6m long and 5m wide, how high is the room?
lawyer [7]

Area of ceiling: 6 x 5 = 30 square meters:

Area of 4 walls = 107 - 30 = 77 square meters

2 walls = 6 + 6 = 12 meters long

2 walls = 5 + 5 = 10 meters long

12 + 10 = 22

77 square meters / 22 meters = 3.5 meters

The walls are 3.5 meters high.

Answer:

Carl traveled 281.25 km by bus and 1,618.75 km by plane.

Step-by-step explanation: v1 = 60 km/h average speed by bus to Toronto

v2 = 700 km/h average speed by plane to Winnipeg

d = 1,900 km the total distance traveled

t = 7 h total traveling time

t1 = the time of the travel by bug

t2 = the time of the travel by plane

t = t1 + t2 the total time

d1 = the distance traveled by bus

d2 = the distance traveled by plane

d = d1 + d2 the total distance

Since average speed = distance/time we have time = distance/avg.speed

t1 = d1/v1 that is t1 = d1/60

t2 = d2/v2 that is t2 = d2/700

Plug the above values into t1 + t2 = t.

We have the following system of equations:

d1/60 + d2/700 = 7

d1 + d2 = 1900

.......

Click here to see the step by step solution for 'd1' and 'd2'

.......

d1 = 281.25 km

d2 = 1,618.75 km

Carl traveled 281.25 km by bus and 1,618.75 km by plane.
