Hexaware Speed Time and Distance Quiz 1

Distance Travelled = \frac{12000}{1000} = 12 km

Downstream rate = \frac{36}{3} = 12

Upstream rate = \frac{18}{3} = 6

Rate of Stream =  \frac{1}{2}\times (12-6) = 3km/hr

Speed = \frac{3200}{40} = 80 m/sec

If distance is constant then ratio of Speed is inversely proportional to their Time Taken Respectively.

Ratio of Time Taken  = 2 :3

Ratio of Speed = \frac{1}{2} : \frac{1}{3} =3:2

 

When there will be same direction Relative speed will be difference of speed

Relative speed = 112 - 100 = 12 km/hr

Time is directly proportional to Distance Traveled

If Distance doubled then Time  increased to double of earlier

Suresh Speed = \frac{200}{5} = 40 m/sec

Ramesh speed = 2\times 40 = 80 m/sec

Speed = \frac{1200}{20} = 60 m/sec

50 \times \frac{3}{50} = 3 km\hr

Time Required to cover 19 Rounds = 19 \times 3 = 57 minutes
