what is the value of y?
Answers
Step-by-step explanation:
40 kmph or 40 km/h
Step-by-step explanation:
let the distance from souce to destination be y
and the avarage speed for 2nd jounet be x (not a 2 variable equation)
time taken in 1st journey = distance/time =y/60
time taken in 2nd journey = distance/time = y/x
time taken for whole journey = total distance/ speed (speed here is avarage) = 2y/48
also total time = time taken in 1st journey+ time taken in 2nd journey
2y/48 = y/60 + y/x
2/48 = 1/60 + 1/x
1/24 = 1/60 + 1/x
1/24 - 1/60 = 1/x
(5-2)/120 = 1/x
3/120 = 1/x
1/40 = 1/x
40 = x
x = 40
x = 40 km or ≈ 11.12 m
