Correct Answer - Option 1 : 36000
Given :
Speed of Rahul from home to temple = 54 km/hr
Speed of Rahul from temple to home = 72 km/hr
Formula Used:
Distance = Speed × time
x km/hr = x × (5/18) m/s
Calculation:
let the distance be x
speed of Rahul in m/s = 54 × (5/18) = 15 m/s
⇒ speed of rahul in return in m/s = 72 × (5/18) = 20 m/s
⇒ Total time = 70 minutes
⇒ (x/15) + (x/20) = 70 × 60
⇒ x = (15 × 20 × 70 × 60)/35 = 36000 m
∴ Distance between his home and temple is 36000 meters
