Question

a) A car covers a distance of 89.1 km in 2.2 hours. What is the average distance covered
by it in 1 hour?
b) The length of the rectangle is 7.1cm and its breadth is 2.5cm. What is the area of the
rectangle?

Answer 1

Answer:

44.55 km

Step-by-step explanation:

89 is total km in 2 HR so we want 1 hr km half the the time with the value total distance

Answer 2

Answer:

The average distance covered by car in 1 hour is 40.5 km.

Step-by-step explanation:

We are given that a car covers a distance of 89.1 km in 2.2 hours and we have to calculate the average distance covered by it in 1 hour.

We will use the concept of unitary method here, that is;

If the value of more than 1 item is given and we have to calculate the value of 1 item, then we will use division.

If the value of only 1 item is given and we have to calculate the value of more than 1 item, then we will use multiplication.

So, here we know the distance covered by the car in 2.2 hours and we have to find the distance covered in 1 hour, so we will use division.

Distance covered by the car in 2.2 hours = 89.1 km

Distance covered by the car in 1 hour = 89.1/2.2  km

                                                              =  891/22  =  40.5 km

b. Area of rectangle = l*b

= 71/10*25/10

= 71/10*5/2

= 17.75 $cm^{2}$
