Question

A plane flies x mph. How far can it go in y hours? Which expression represents this? x/y miles xy miles x + y miles

Answer 1

x mi/h *y h = xy (mi*h)/h  = xy mi,

or you can use formula Distance = speed * time
speed = x mph
time =y hours
Distance =x*y (mi)

Answer : xy mi

Answer 2

The required expression is the equation which represents the distance covered by the plane traveling at a speed of x mph in y hours which is the product of the speed and time of travel of the plane, which is XY miles.

• Speed of plane = x mph

• Time of travel = y hours

The distance covered by the plane can be calculated using the distance formula :

• Distance = Speed × time

• Distance = xy miles

Therefore, the distance traveled by the plane after y hours ls XY miles
