Question

Kaushal travelled for 14 hours 28 minutes at the speed of 90 km/h. At what speed (in km/h) should he travel to cover the same distance in 7 hours?

This question was previously asked in
RRB Group D 2025 Question Paper (18-Aug-2026) (Shift 1)
The correct answer is

186

14 hours 28 minutes = 14 + \(\frac{28}{60}\) hours = \(\frac{217}{15}\) hours.

Distance = 90 × \(\frac{217}{15}\) = 6 × 217 = 1302 km.

Required speed = \(\frac{1302}{7}\) = 186 km/h.

Hence, the answer is 186.
