Answer 1

Answer:

3/5km/h and 4cm

Step-by-step explanation:

Distance = 100m = 100/1000km = 1/10km

Time = 1/6 hour

Speed Distance/time = (1/10 ÷ 1/6)km/h

= (1/10 × 6/1)km/h=6/10km/h =3/5 km/h

23. Let the height be Xcm.

Volume of fish tank = l × b × h = 25cm × 20cm × Xcm = 500X cm^3

But it is given that the volume of the tank is 2 l.

So, 500Xcm^3 = 2l

or, 500Xcm^3 =2 × 1000cm^3

X = 2000/500 cm = 4cm
