Answer:
The speed of car B is 50 mile per hour
Step-by-step explanation:
Given as :
The Distance travel by car A = 175 miles
The Distance travel by car B = 125 miles
The Time taken by both car A and B is same = T hours
Let The speed of car B = S mile per hour
So, The speed of car A = ( S + 20 ) mile per hour
Now, Time =
So , For Car A ,
T =
For Car B ,
T =
So, =
Or, 175 × S = 125 × ( S + 20 )
Or, 175 S - 125 S = 125 × 20
Or, 50 S = 2500
∴ S =
I.e S = 50 mph
And S + 20 = 50 + 20 = 70 mph
The speed of car A = 70 mph
The speed of car B = 50 mph
Hence The speed of car B is 50 mile per hour Answer
