Question

The average speeds of 3 vehicles A, B and C are 18 km/h, 17 m/s and 2 km/ min respectively arrange them in ascending order

Answer 1

_______________________________

Solution:

Given ,

• Average speed of A = 18km/h
• Average speed of B = 17m/s
• Average speed of C = 2 km/min

We need to find

• Arranging the speeds of vehicles in ascending order

________________________

We need to arrange in ascending order so , we have to convert all the units into one unit

Now , converting all the units into m/s

★ Case 1

18 km/h → m/s

To convert we need to multiply with 5/18

18 × 5/18

18km/h = 5 m/s

★ Case 2

17 m/s

It is already in m/s so , no need to convert

★ Case 3

2 km/min → m/s

Now , substituting 1 min = 60s & 2 km = 2000m

2km/min → 2000/60

2km/min = 33.33 m/s

_______________________

Now , comparing

33.33 m/s > 17 m/s > 5 m/s

C > B > A.

In ascending order

A < B < C. [ answer ]
