Question

In 10 minutes a truck whose speed is 30 km/h travels a distance of: (a) 50 km (b) 3.5 km (c) 14 km (d) None of these​

Answer 1

Answer:

Distance = speed × time= 30 × 5/18 × 10 × 60 ( we have to take 5/18 in the formula to convert speed into m/s and we have to take multiplication with 60 to convert minutes into seconds )

Now, distance= 150/ 18 × 600 = (90/ 18 × 1000) m= 5 km
