Question

draw a graph to convert miles to kilometre given 1 miles 1.6 km use the graph to find how many kilometre are approximately equal to 4.5 miles How many miles are approximately equal to 8 km

Answer 1

I don't by the graph way but I can answer it simpler way .

We have been given that 1 mile= 1.6 kilometres

We also know that 1km=1000metres so

by multiplying on both sides

1.6×1000=1×1000

1600m is to 1000m

This means that miles and kilometres are in ratio of

1.6:1 so...

(a)4.5×1.6

=9.20km

This means that 4.5 miles is equal to 9.20km

(B)we have been given that 1mile = 1km so...

let's take the H as no. of miles so...

H×1.6=8

taking left hand side and right hand side.

H=8÷1.6

H = 5

approximately 5 miles will be equal to 8 km
