Answer:

45 3/10 miles per hour

Step-by-step explanation:

Distance travelled by the car = 30 1/5 miles

Time taken = 2/3 of an hour

Average speed = distance travelled / time taken

= 30 1/5 miles ÷ 2/3 of an hour

= 151/5 ÷ 2/3

= 151/5 × 3/2

= (151 * 3) / (5 * 2)

= 453 / 10

= 45 3/10 miles per hour

Average speed = 45 3/10 miles per hour

Sally has 2 cats and each cat eats 1/4 of a tin of cat food each day.
Mashutka [201]

If one cat eats 1/4 of a tin per day then two cats eat 1/2 of a tin per day.

We have 9 tins so if each day cats eat 1/2 we have to divide 9 with 1/2 and we get 18 which is for how many days she can feed the cats until she runs out of food.

Hope this helps.
