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

Thank u

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.
