The scale of a map is 1:1,000,000. What are the real distances between two points if the distance between them on this map is 35

Inessa [10]

35km; Since the points on the map are one millionth of their actual size, simply multiply by one million and convert from there.

35*1,000,000 = 35,000,000mm

35,000,000/1000 = 35,000m

35,000/1000 = 35km

It's asking you to work out how many minutes it will take to drive to a school if you're driving at a speed of 35 miles per hour (mph).

But there's a problem with the question because it doesn't tell you how far away the school is.

But this is how you are supposed to do it:

Distance ÷ 35 = answer (in hours)
Answer (in hours) × 60 = Final answer (in minutes).

It's like this because time = distance ÷ speed, and the question asks for the answer in minutes, but the unit is in miles per hour, so you multiply by 60 to get the answer in minutes.

Hope I helped :)

Answer:

c - 39

Step-by-step explanation:

Given,

-4 (8 - c ) - (3c + 7 )

= -4 ( -c + 8 ) - (3c + 7 )

= 4c - 32 - ( 3c + 7 )

= 4c - 32 - 3c - 7

= ( 4 - 3 )c + ( -32 - 7 )

= c + ( -32 - 7)

= C - 39

hope this answer helps you dear! take care!
