Word Problems:
1. A car travels 100 miles is 3 hours (with a constant speed). How far will it
take to travel 200 miles.
50 apples cost of Rs 25.How much would 75 apples cost.

see explanation

Step-by-step explanation:

1) 100miles in 3 hrs

then let 200 miles in X hour.

now 100/200=3/X

or, 100 X =3×200

or, X = 3×200/100

or, X =6 hrs

so 6 hrs will it take to travel 200 miles.

2) 50 apples cost rs.25

let 75 apples cost rs. X

now 50/75=25/X

or, X = RS. 25×75/50

or, X = RS. 37.5

hope this will help you.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
