Question

Alight is plotted on a map having the scale 1 inch = 400 miles. On the map it is 9 % inches from point A to point B. If a plane flies this distant at the speed of 300 mph, how ong will the trip take?

Answer 1

12 hours

Explanation:

Given

1 inch = 400 miles

1 inch = 400 miles

multiplying LHS and RHS by 9

1*9 inche = 400*9 miles

9 inches = 3600 miles

Given that on map distance from point A to point B is 9 inches

Actual distance will be 3600 miles as calculated above.

we know that

Time = distance / speed

given

speed = 300 mph

distance = 3600 miles

time = 3600 miles/300 mph = 12 hours

Thus, trip will take 12 hours.
