Solved this question with explanation
​

Answer 1

Rohan can walk 5 km in 2 hours 30 minutes.

Step-by-step explanation:

Distance walked by Rohan = D = 3 km

Time = T = 1 hours 30 minutes = $1\frac{30}{60} = 1\frac{1}{2} = \frac{3}{2} \ hours$

Speed = $\frac{D}{T} = \frac{3}{(\frac{3}{2})} = 2 \ km/hr$

Given, T = 2 hours 30 minutes = $2\frac{30}{60} = 2\frac{1}{2} = \frac{5}{2} \ hours$

Distance = D = S x T = 2 x $\frac{5}{2}$ = 5 km

Hence, Rohan can walk 5 km in 2 hours 30 minutes.

Answer 2

Step-by-step explanation:

Answer is 5 km..

30 + 30 = 90 minutes

1 hour 30 minutes = 180 / 30 = 6 km

2 hours 30 minutes = 150 / 30 = 5 km

Thus, 5 km is the answer...................,..........
