Question

A plane is flying from City A to City B at m miles per hour. Another plane flying from City B to City A travels 50 miles per hour faster than the first plane. The cities are R miles apart. If both planes depart at the same time, in terms of R and m, how far are they from City A when they pass?

(A) R/m + 50
(B) Rm/(2m) – 50
(C) Rm/(2 + 50m)
(D) (R + 50)/(m + 50)
(E) (m + 50)/R

(A) R/m + 50
(B) Rm/(2m) – 50
(C) Rm/(2m + 50)
(D) (R + 50)/(m + 50)
(E) (m + 50)/R

You sure all the options are correct.?

TarunKumar1234 · Answer

Given, speed of A= m, speed of B = 50+m

Time to meet = T= D/S = R/(m+50+m)= R/(50+2m)

Distance from A = Time to meet * Speed of A = R/(50+2m) *m = mR/(50+2m)

Bunuel I think option needs to be corrected. Please review the same.

Given: 
Speed from A to B: m miles/hrs
Speed from B to A: 50 + m miles/hrs
Distance b/w A and B = R miles.

Time after which they will meet = Total Distance/Relative Speed = R/(50 + 2m) hrs.

Distance from M when they Pass = mR/(50 + 2m).

Answer: mR/(50 + 2m) miles.

Bunuel  could you kindly recheck the options.
Thanks.
