On a circular path of 2742 m, Riya and Trisha start walking from the same point but in opposite directions at the speed of 4.6 m/s and X m/s, respectively. They will meet for the first time after 457 seconds. Find the value of X.​

Correct option is D

Given:

Length of circular path = 2742 m

Speed of Riya = 4.6 m/s

Speed of Trisha = X m/s

Time to meet = 457 seconds

Formula Used:

Distance = (Speed1 + Speed2) × Time

Solution:

2742 = (4.6 + X) × 457

$$\frac{2742}{457}$$​ = 4.6 + X

6 = 4.6 + X

X = 6 - 4.6 = 1.4 m/s
