One plane can travel 20 miles per hour faster than another. One of them goes 285 miles in the same time it takes the other to go

Hatshy [7]

Answer:

$\huge\fbox{Answer ☘}$

$\bold\blue{190 \:miles/hr \:and \:170 \:miles/hr}$

Step-by-step explanation:

Let the speed of faster plane be x

therefore ,

speed of slower plane = x - 20

As the time taken is same ,

$\frac{285}{x} = \frac{255}{x - 20} \\ \\ \frac{57}{x} = \frac{51}{x - 20} \\ \\ 57(x - 20) = 51x \\ \\ 6x = 1140 \\ \\ x = 190$

therefore ,

faster plane travels at a speed of 190 miles/hr

while..

the slower plane travels at a speed = ‎ ‎ ‎ ‎ ‎ ‎( 190-20 ) miles/hr

‎ ‎ ‎ ‎ ‎‎ ‎ ‎ ‎ ‎‎ ‎=> 170 miles/hr

hope helpful~
