Answer 2

Answer:

1 and ) The whole sum is in the S.I. Unit:

Speed= 75km/hr

= \frac{75×1000}{60×60}

60×60

75×1000

m/s

= \frac{125}{6}

6

125

m/s

1) Time= 20 mins= 20×60 secs= 1200secs

Distance = Speed×Time

D= \frac{125}{6}

6

125

×1200 metres

D= 25000 m= 25 km

2) Distance= 250km = (250×1000) metre, Speed=\frac{125}{6}

6

125

Time=\frac{Distance}{Speed}

Speed

Distance

T=12000secs= 3.33 hour
