2.3/-8
3.2/6
4.3/6

2..

of its length. Find its dimensions.

1.1.2m;1m
2.0.3m:0.2m
3.0.9m;06m

3.Moyle drives his car 150 km in 3 hours. Find the unit rate.
[1] Moyle drives 50 km per hour.
[2] Moyle drives 1 km per 50 hours.
[3] Moyle drives 150 km per 3 hours
[4] Moyle drives 30 km per hour.

Answer 1

1.$\frac{3}{6}$,

when simplified, i.e. by dividing both the numerator and denominator by 3, the answer is$\frac{1} {2}$.

2. 0.9m;0.6m

Perimeter of a rectangle =2(L+W)

3=2(L+$\frac{2}{3}$ L)

3=(2L+$\frac{4}{3}$ L)

3=$\frac{10}{3}$ L

L=$\frac{9}{10}$ m

L=0.9m

W=$\frac{2}{3}$ ×L=$\frac{2}{3}$ × 0.9=0.6m

Answer is 0.9m;0.6m.

3.Speed =$\frac{Distance} {Time}$ =$\frac{150} {3}$ =50 km/hr

Thus, Moyle drives 50km per hour
