Answers
Answer:
9.2km
Step-by-step explanation:
Let us keep both the friends name as A and B respectively.
The distance is in kilometre
so both friends speed should be in km/h
A speed = 4km/h
B speed = 4 × 18/5
= 72/5km/h
time=30minutes
Convert it into hours
=30/60
Distance = Total speed × Time
= (4 + 72/5) × 30/60
= 92/5 × 30/60
= 92÷10
=9.2km

Answer:
Answer is 9.2 km
Step-by-step explanation:
Let the two friends be X and Y respectively.
Distance is in kilometers.
so both the X and Y speed should be in km/h
Speed of X = 4km/h
Speed of Y = 4 M/s = 4 × 18/5 = 72/5 km/h
Given that,
Time = 30 min = 30/60 h
Distance = Total speed × Time
= {4 + 72/5} × {30/60}
= { 20 + 72/5} × {1/2}
= (92/5) × (1/2)
= 92/10
= 9.2 km
Therefore, Distance = 9.2 km.
