Answer 2

Step-by-step explanation:

Given Four people A, B, C and D are travelling with a speed of 4.5 km/h, 1.5 m/s, 160 cm/s and 3 mi/hr respectively. Which of the  following represents the people arranged in increasing order of  their speeds?

• Now we need to find the people arranged in increasing order of their speeds.
• So we have  
• 4.5 km/hr
• 1.5 m/s
• 160 cm/s
• 3 miles/hr
• We can convert all the speeds into one unit that is to m/s. So we get
• 1 km/hr = 0.27 m/s
• 4.5 km/hr will be 4.5 x 0.27 = 1.21 m/s
• 1 cm/s = 0.01 m/s
• 160 cm/s will be 160 x 0.01 = 1.6 m/s
• 1 mi/hr = 0.44 m/s
• 3 mi/hr will be 0.44 x 3 = 1.32 m/s
• So we can write this as 1.21, 1.5, 1.6,1.32.
• Now arranging this in increasing order we get
• 1.2, 1.32, 1.5, 1.6
