An airplane leaves Los Angeles and travels five hours to New YorkCity. The return trip travels along the same route and takes si
finlep [7]

The distance of the plane flies between the two cities is 1,113.75  miles

The formula for calculating the distance travelled is expressed as:

D = vt where:

v is the speed

t is the time taken

Given the following:

v = 99mi/hr

Total time taken = 5hr + 6.25hr

Total time taken = 11.25hr

Get the required distance

Distance = 99mi/hr * 11.25hr

Distance = 1,113.75miles

Hence the distance of the plane flies between the two cities is 1,113.75  miles
