Understand Accurate Conversions Between Miles and Kilometres Worksheet

Let's recap, miles and kilometres are used to measure distance.

An old Roman mile was 1000 paces, each of 2 steps. A kilometre is a metric measurement, equivalent to 1000 metres.

8 kilometres = 5 miles

1 kilometre = 5 ÷ 8 = 0.625 miles

Therefore, a kilometre is less than a mile.

To convert kilometres to miles you need to ÷ 8 and x 5

To convert miles to kilometres you need to ÷ 5 and x 8

Example

To convert 56 kilometres into miles

56 ÷ 8 = 7

7 x 5 = 35 miles

ANSWERS

Question 1

The distance from London to Glasgow is 415 miles.

Convert this into kilometres.

CORRECT ANSWER

EDDIE SAYS

Remember, the rule to convert miles to kilometres is ÷ 5 and x 8 415 ÷ 5 = 83 83 x 8 = 664 km

ANSWERS

Question 2

A lorry driver has undertaken a lot of journeys in 7 days.

He has covered a distance of 624 km.

Can you convert this into miles?

CORRECT ANSWER

EDDIE SAYS

Remember in order to convert km to miles, we ÷ 8 and then x 5. 624 ÷ 8 = 78 78 x 5 = 390 miles

ANSWERS

Question 3

A racetrack is 4.5 miles long.

What would the length be in km?

fast car

CORRECT ANSWER

7.2 km

EDDIE SAYS

This was a tricky one as we had to convert a decimal number. 4.5 miles ÷ 5 = 0.9 0.9 x 8 = 7.2 km

ANSWERS

Question 4

A racetrack is 3.2 km long.

What would the length be in km?

CORRECT ANSWER

2.0 miles

EDDIE SAYS

Again, this question requires that we calculate carefully with decimal numbers. 3.2 km ÷ 8 = 0.4 0.4 x 5 = 2.0 miles

ANSWERS

Question 5

A racetrack is 7.5 km long.

What would the length be in miles?

CORRECT ANSWER

4.7 miles

EDDIE SAYS

Remember the formula for converting km to miles? 7.2 km ÷ 8 = 0.9375 0.9 x 5 = 4.6875 miles To 1 d.p. we would round it to 4.7 miles.

ANSWERS

Question 6

A racetrack is 7.9 miles long.

What would the length be in kilometres?

CORRECT ANSWER

12.64 km

EDDIE SAYS

7.9 miles ÷ 5 = 1.58 1.58 x 8 = 12.64 km Great focus, keep it up! You're past halfway in the activity.

ANSWERS

Question 7

Can you match the distance in miles with the equivalent distance in kilometres?

CORRECT ANSWER

Column A	Column B
5 miles	8 km
4 miles	6.4 km
2 miles	3.2 km
6 miles	9.6 km

EDDIE SAYS

To correctly match up the number of miles to the corresponding kilometres, we need to ÷ 5 then x 8. 5 miles = 8 km 4 miles = 6.4 km 2 miles = 3.2 km 6 miles = 9.6 km

ANSWERS

Question 8

How many miles are there in 2 kilometres?

CORRECT ANSWER

1.25 miles
1.25

EDDIE SAYS

Remember to convert kilometres to miles, we have to ÷ 8 and then x 5. 2 ÷ 8 = 0.25 0.25 x 5 = 1.25 miles This should be like second nature to you now!

ANSWERS

Question 9

How many kilometres are there in 10 miles?

CORRECT ANSWER

16 km
16

EDDIE SAYS

The rule to convert miles to kilometres is ÷ 5 and then x 8. So, 10 ÷ 5 = 2 2 x 8 = 16 km

ANSWERS

Question 10

A can of cola is 10 cm high.

If the cans were laid end to end, how many cans would be needed to cover a distance of 1 mile?

CORRECT ANSWER

EDDIE SAYS

To work through this problem, we have to work out the distance different amounts of cans could cover. 1 can = 10 cm Remember there are 100 cm in 1 metre therefore 10 cans = 1 metre Remember there are 1000 metres in 1 km therefore 10,000 cans = 1 km So to work out the number of cans in 1 mile, we need to multiply 10,000 by 1.6 as 1.6 km = 1 mile 10,000 x 1.6 = 16,000 16,000 cans covers 1 mile Great focus, that’s another activity completed!
