Question

9. A car runs at a speed of 90 km/hr. What distance does it cover in 50 minutes?
(a) 75 km
(b) 65 km
(c) 52 km
(d) 72 km​

Answer 1

Answer:

50 minutes means 50/60 hours = 5/6 hours

so, distance covered by car = speed × time

=> distance covered by car = 90 × 5/6 = 75 km

Answer 2

Answer:

A) 75km

Step-by-step explanation:

x= u×t

 where x= distance covered, u = speed of the car and t = time taken by the car to cover this much distance.

x= 90 ×(50/60)                        time and speed must be n same units

 = 90×5/6                                           50 min= (50/60) hours

= 15×5

x= 75 km
