(total 5 marks) 4) complete the following and show your work. a) convert 2.5 km into cm. (1 mark) b) convert 500 ft into cm using 1 inch 2.54 centimeters; and 12 inches - 1 foot. (2 marks)

2.5 km  = 250000 cm

500 ft = 15240 cm

Explanation:

part a

given data

length = 2.5 km

to find out

Convert into cm

solution

we know that 1 m = 100 cm    1

and also we know 1 km = 1000 m     2

sop as that we can say from equation 1 and 2

1 km = 100000 cm

so for 2.5 km = 2.5 × 100000 cm

2.5 km  = 250000 cm

and

part b

given data

length = 500 ft

to find out

Convert ft into cm

solution

we know here that

1 ft = 12 inches     1

and also we know 1 inch = 2.54 cm    2

so we can say

500 ft = 12 × 500 inches

500 ft = 6000 inches

and 500 ft = 6000 × 2.54 cm

500 ft = 15240 cm

thats correct, but whats the question
