Question

5. If Nitin covers 2/5 of a journey by car and 1/5 using bicycle. What part of the journey is covered by Nitin?​

Answer 1

Distance = 9.5 km

Step-by-step explanation:

Distance covered in 1 hr = 3 4/5 km = 19/5 km

Distance covered in 2 1/2 hrs. or 5/2 hrs. = (19/5) * (5/2)

= 19/2 km or 9.5 km

2. By using formula, Speed = Distance/Time

Nitin covers 3 4/5 km (19/5 km) in 1 hr, therefore, his speed is 19/5 km/hr

We are given, Time = 2 1/2 hr. =5/2 hrs.

We know, Speed = Distance/Time

So, 19/5 = Distance / (5/2)

Distance = (19/5) * (5/2)

Distance = 9.5 km
