If one plane is flying at 40 mph while another is flying at 100 mph, and they are 200 miles apart and flying directly towards each other, how long will it take them to meet?

 Time taken them to meet = 1.429 hours.

Explanation:

 Speed of first plane = 40 mph

 Speed of second plane = 100 mph

 Distance between planes = 200 miles

 If two objects with speed v and u are flying towards each other, their relative speed = v + u

 So here relative speed = 40 + 100 = 140 mph

 Time taken to meet = Distance/Speed = 200/140 = 1.429 hours.

 Time taken them to meet = 1.429 hours.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
