Question

If Shikha covers certain distance on her car at 60 km/hr in 2 hours and 30 minutes then find the speed of Shikha's car to travel the same distance in 4 hrs.

• A. 47.5 km/hr
• B. 35 km/hr
• C. 37.5 km/hr
• D. 44 km/hr

Answer 1

Answer:

C. 37.5 km/hr

The distance covered in both cases is the same. S1 × T1 = S2 × T2 ⇒ 60 × 2.5 = S2 × 4 ⇒ 60 × (5/2) = S2 × 4 ⇒ S2 = 150/4 ⇒ S2 = 37.5 km/hr
