504/9= 56
504/8= 63
504/7= 72
504/6= 84

With a headwind a plane traveled 128 km in 2h. The return trip with a tail wind took 24 min less. Find the air speed of the plan
sertanlavr [38]

Based on the information given, it can be noted that the air speed that the plane has will be 71.1 km per hour.

The number of hours used for the return trip will be:

= 2 hours - 24 minutes.

= 1 hour 36 minutes.

= 1.6 hours.

Therefore, the speed of the air plane will be:

= (128 + 128) / (2 + 1.6)

= 256/3.6.

= 71.1 km per hour.

How Do I solve this!

Answer:

1380 in²

Step-by-step explanation:

The lateral surface is the sum of the areas of all the sides, or 'faces'.

The bases (the top and bottom) are <u>not </u>included.

This is a prism with triangles for bases (at each end). The sides are rectangles.

Add up the areas of the rectangles.

300 + 480 + 600 = 1380
