A car travels at a speed of 80 km/hr and covers a particular distance in 4 hour 30 minutes. How much time (in hours) another car travelling at the speed of 30 km/hr will take to cover the same distance?
Show answer & explanation
Correct answer: B
Explanation
Given:
Speed₁ = 80 km/h, Time₁ = 4.5 hours
Speed₂ = 30 km/h
According to the formula:
Distance = Speed × Time
Distance = 80 × 4.5 = 360 km
Time₂ = 360 / 30 = 12 hours
